Xavier Morel <xavier.mo...@masklinn.net> added the comment: I have not noticed anything, I was just looking at the bytecode changes and stumbled upon this oddity. Though I would expect a small slowdown as every fn(**kw) would now incur an extra dict copy, unless there’s something in call_function_ex which copies the input dict iff its ref count is not one?
For whatever that’s worth, the 3.8 bytecode has been there since call_function_ex was added in 3.6 and before that call_function_kw looks identical (load_global foo, load_local var, call_function_kw) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42033> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
