Batuhan Taskaya <isidenti...@gmail.com> added the comment: I've given this another shot, but even though I was able to create a patch that preserved slices as (type(slice), start, stop, step) tuples in the consts_cache, this final optimization prevented me to finalize it; 😃https://github.com/python/cpython/blob/master/Python/compile.c#L5855-L5858
So, unless anyone else came up with a reasonable idea to do this optimization at the compile-time without actually making them hashable, I am re-proposing the idea of making them hashable. Pro: - Up to %30+ speedup on slicing with constants (extremely common) Cons: - Mappings accepts slices, which would rarely lead some esoteric cases (like the examples given) Comments would be appreciated ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42454> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
