"When dealing with complex template tuples, it's very easy to overflow the
maximum symbol length allowed by OPTLINK. This is, simply put, a damn shame,
because it prevents otherwise completely legal code from compiling and linking
with DMDWin, whereas it works perfectly fine when using DMDNix or GDC.
I know that this is neither a simple nor a small issue to fix: either the
ancient, nearly-immutable OPTLINK would have to be modified, or DMDWin would
have to be changed to output a more reasonable format, in which case a new
linker would probably have to be written. Until then, this issue should stand
as a reminder that DMDWin is inherently limited.
Oplink isn't the issue. The OMF file format has a hard limit. This results in
the only solutions being: convert DMD to use some other .obj format or have DMD
do something else for name mangling.
In talking to Walter, the issue is that it's easy to get symbols that have more
info in them than can be fit into the limit. (the limit has already stretched
by gziping the symbols.)
The simple solution I have proposed is to just MD5 (or what not) the symbols.
The only issue (besides a vanishingly small chance of a hash collision) is that
this looses information so you can't look at a symbol and directly determine
what it was. My answer to that is, who cares? The only place where hashing
provides less info than compressing is in a debugger and it can grab the full
symbol from a table in the static data segment.
I suppose as a stopgap measure that'd work fine, and might even be controlled
by a compiler switch, so that in the general case debugger info wouldn't be
affected. And what's more -- the only time these issues come up is with
templates, which a lot of debuggers have serious problems with anyway, so..
I would set it up as a method of last resort. It wouldn't be used unless the
symbol can't be used any other way.

/**
Retrieves the members of an enumerated type $(D enum E).
Params:
E = An enumerated type. $(D E) may have duplicated values.
Returns:
Static tuple composed of the members of the enumerated type $(D E).
The members are arranged in the same order as declared in $(D E).
Note:
An enum can have multiple members which have the same value. If you want
to use EnumMembers to e.g. generate switch cases at compile-time,
you should use the $(REF NoDuplicates, std,meta) template to avoid
generating duplicate switch cases.
Note:
Returned values are strictly typed with $(D E). Thus, the following code
does not work without the explicit cast:
--------------------
enum E : int { a, b, c }
int[] abc = cast(int[]) [ EnumMembers!E ];
--------------------
Cast is not necessary if the type of the variable is inferred. See the
example below.
Example:
Creating an array of enumerated values:
--------------------
enum Sqrts : real
{
one = 1,
two = 1.41421,
three = 1.73205,
}
auto sqrts = [ EnumMembers!Sqrts ];
assert(sqrts == [ Sqrts.one, Sqrts.two, Sqrts.three ]);
--------------------
A generic function $(D rank(v)) in the following example uses this
template for finding a member $(D e) in an enumerated type $(D E).
--------------------
// Returns i if e is the i-th enumerator of E.
size_t rank(E)(E e)
if (is(E == enum))
{
static foreach (i, member; EnumMembers!E)
{
if (e == member)

$(RED Warning: This trait will be deprecated as soon as it is no longer used
in Phobos. For a function parameter to safely accept a type
that implicitly converts to string as a string, the conversion
needs to happen at the callsite; otherwise, the conversion is
done inside the function, and in many cases, that means that
local memory is sliced (e.g. if a static array is passed to
the function, then it's copied, and the resulting dynamic
array will be a slice of a local variable). So, if the
resulting string escapes the function, the string refers to
invalid memory, and accessing it would mean accessing invalid
memory. As such, the only safe way for a function to accept
types that implicitly convert to string is for the implicit
conversion to be done at the callsite, and that can only occur
if the parameter is explicitly typed as an array, whereas
using isConvertibleToString in a template constraint would
result in the conversion being done inside the function. As
such, isConvertibleToString is inherently unsafe and is going
to be deprecated.)
