The zonker in TcHsSyn is careful not to turn the free alpha into Any (as it usually does). Instead it turns it into a TyVar 'a'. See TcHsSyn Note [Zonking the LHS of a RULE]. Now we must quantify over that 'a'. It's /really/ inconvenient to do that in the zonker, because the HsExpr data type is very large. But it's /easy/ to do it here in the desugarer. Moreover, we have to do something rather similar for dictionaries; see Note [Free dictionaries on rule LHS]. So that's why we look for type variables free on the LHS, and quantify over them. Note [Free dictionaries on rule LHS] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When the LHS of a specialisation rule, (/\as\ds. f es) has a free dict, which is presumably in scope at the function definition site, we can quantify over it too. *Any* dict with that type will do. So for example when you have f :: Eq a => a -> a f = <rhs> ... SPECIALISE f :: Int -> Int ... Then we get the SpecPrag SpecPrag (f Int dInt) And from that we want the rule RULE forall dInt. f Int dInt = f_spec f_spec = let f = <rhs> in f Int dInt But be careful! That dInt might be GHC.Base.$fOrdInt, which is an External Name, and you can't bind them in a lambda or forall without getting things confused. Likewise it might have an InlineRule or something, which would be utterly bogus. So we really make a fresh Id, with the same unique and type as the old one, but with an Internal name and no IdInfo. Note [Drop dictionary bindings on rule LHS] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drop_dicts drops dictionary bindings on the LHS where possible. E.g. let d:Eq [Int] = $fEqList $fEqInt in f d --> f d Reasoning here is that there is only one d:Eq [Int], and so we can quantify over it. That makes 'd' free in the LHS, but that is later picked up by extra_dict_bndrs (Note [Dead spec binders]). NB 1: We can only drop the binding if the RHS doesn't bind one of the orig_bndrs, which we assume occur on RHS. Example f :: (Eq a) => b -> a -> a {-# SPECIALISE f :: Eq a => b -> [a] -> [a] #-} Here we want to end up with RULE forall d:Eq a. f ($dfEqList d) = f_spec d Of course, the ($dfEqlist d) in the pattern makes it less likely to match, but there is no other way to get d:Eq a NB 2: We do drop_dicts *before* simplOptEpxr, so that we expect all the evidence bindings to be wrapped around the outside of the LHS. (After simplOptExpr they'll usually have been inlined.) dsHsWrapper does dependency analysis, so that civilised ones will be simple NonRec bindings. We don't handle recursive dictionaries! NB3: In the common case of a non-overloaded, but perhaps-polymorphic specialisation, we don't need to bind *any* dictionaries for use in the RHS. For example (Trac #8331) {-# SPECIALIZE INLINE useAbstractMonad :: ReaderST s Int #-} useAbstractMonad :: MonadAbstractIOST m => m Int Here, deriving (MonadAbstractIOST (ReaderST s)) is a lot of code but the RHS uses no dictionaries, so we want to end up with RULE forall s (d :: MonadAbstractIOST (ReaderT s)). useAbstractMonad (ReaderT s) d = $suseAbstractMonad s Trac #8848 is a good example of where there are some interesting dictionary bindings to discard. The drop_dicts algorithm is based on these observations: * Given (let d = rhs in e) where d is a DictId, matching 'e' will bind e's free variables. * So we want to keep the binding if one of the needed variables (for which we need a binding) is in fv(rhs) but not already in fv(e). * The "needed variables" are simply the orig_bndrs. Consider f :: (Eq a, Show b) => a -> b -> String ... SPECIALISE f :: (Show b) => Int -> b -> String ... Then orig_bndrs includes the *quantified* dictionaries of the type namely (dsb::Show b), but not the one for Eq Int So we work inside out, applying the above criterion at each step. Note [Simplify rule LHS] ~~~~~~~~~~~~~~~~~~~~~~~~ simplOptExpr occurrence-analyses and simplifies the LHS: (a) Inline any remaining dictionary bindings (which hopefully occur just once) (b) Substitute trivial lets, so that they don't get in the way. Note that we substitute the function too; we might have this as a LHS: let f71 = M.f Int in f71 (c) Do eta reduction. To see why, consider the fold/build rule, which without simplification looked like: fold k z (build (/\a. g a)) ==> ... This doesn't match unless you do eta reduction on the build argument. Similarly for a LHS like augment g (build h) we do not want to get augment (\a. g a) (build h) otherwise we don't match when given an argument like augment (\a. h a a) (build h) Note [Matching seqId] ~~~~~~~~~~~~~~~~~~~ The desugarer turns (seq e r) into (case e of _ -> r), via a special-case hack and this code turns it back into an application of seq! See Note [Rules for seq] in MkId for the details. Note [Unused spec binders] ~~~~~~~~~~~~~~~~~~~~~~~~~~ Consider f :: a -> a ... SPECIALISE f :: Eq a => a -> a ... It's true that this *is* a more specialised type, but the rule we get is something like this: f_spec d = f RULE: f = f_spec d Note that the rule is bogus, because it mentions a 'd' that is not bound on the LHS! But it's a silly specialisation anyway, because the constraint is unused. We could bind 'd' to (error "unused") but it seems better to reject the program because it's almost certainly a mistake. That's what the isDeadBinder call detects. Note [No RULES on datacons] ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Previously, `RULES` like "JustNothing" forall x . Just x = Nothing were allowed. Simon Peyton Jones says this seems to have been a mistake, that such rules have never been supported intentionally, and that he doesn't know if they can break in horrible ways. Furthermore, Ben Gamari and Reid Barton are considering trying to detect the presence of "static data" that the simplifier doesn't need to traverse at all. Such rules do not play well with that. So for now, we ban them altogether as requested by #13290.

The zonker in TcHsSyn is careful not to turn the free alpha into Any (as it usually does). Instead it turns it into a TyVar 'a'. See TcHsSyn Note [Zonking the LHS of a RULE]. Now we must quantify over that 'a'. It's /really/ inconvenient to do that in the zonker, because the HsExpr data type is very large. But it's /easy/ to do it here in the desugarer. Moreover, we have to do something rather similar for dictionaries; see Note [Free dictionaries on rule LHS]. So that's why we look for type variables free on the LHS, and quantify over them. Note [Free dictionaries on rule LHS] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When the LHS of a specialisation rule, (/\as\ds. f es) has a free dict, which is presumably in scope at the function definition site, we can quantify over it too. *Any* dict with that type will do. So for example when you have f :: Eq a => a -> a f = <rhs> ... SPECIALISE f :: Int -> Int ... Then we get the SpecPrag SpecPrag (f Int dInt) And from that we want the rule RULE forall dInt. f Int dInt = f_spec f_spec = let f = <rhs> in f Int dInt But be careful! That dInt might be GHC.Base.$fOrdInt, which is an External Name, and you can't bind them in a lambda or forall without getting things confused. Likewise it might have an InlineRule or something, which would be utterly bogus. So we really make a fresh Id, with the same unique and type as the old one, but with an Internal name and no IdInfo. Note [Drop dictionary bindings on rule LHS] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drop_dicts drops dictionary bindings on the LHS where possible. E.g. let d:Eq [Int] = $fEqList $fEqInt in f d --> f d Reasoning here is that there is only one d:Eq [Int], and so we can quantify over it. That makes 'd' free in the LHS, but that is later picked up by extra_dict_bndrs (Note [Dead spec binders]). NB 1: We can only drop the binding if the RHS doesn't bind one of the orig_bndrs, which we assume occur on RHS. Example f :: (Eq a) => b -> a -> a {-# SPECIALISE f :: Eq a => b -> [a] -> [a] #-} Here we want to end up with RULE forall d:Eq a. f ($dfEqList d) = f_spec d Of course, the ($dfEqlist d) in the pattern makes it less likely to match, but there is no other way to get d:Eq a NB 2: We do drop_dicts *before* simplOptEpxr, so that we expect all the evidence bindings to be wrapped around the outside of the LHS.
