I don't like co_annotations. * It changes PyCode_NewXXX() API. * Many functions don't have annotations. Adding annotation to code object makes code object fatter even if the function doesn't have annotation. * Code object is immutable & hashable. Adding annotation to code object makes == and hash() complex. * We may introduce lazy loading for docstring and annotation in the future. func.__annotations__ = ('x', 'int', 'z', 'float', 'return', 'Hoge') is much better because: * Zero overhead for functions without any annotations. * After annotation dict is created, the tuple can be released. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42202> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
