# Utilize last character gap for two-way periodic needles # Feature or enhancement ### Proposal: Two-way algorithm currently does not incorporate *Horspool skip rule* when needle is periodic. As part of my work this led to difficulties in run-time predictions. This rule is a significant determinant of run-tim...

# [C API] Split large object.h file: create refcount.h The `Include/object.h` header file became quite big (1260 lines of C code). A large part of it is just reference count management. I propose adding a new `Include/refcount.h` header file to ease the navigation in `Include/object.h` and ease the maintenance of the ...

Other solution is to make `PhotoImage.get()` always returning a 3-...
