[Python-ideas] C#-style "as" casting syntactic sugar for type hints

This is some real code I wrote the other day: payload = { "birthDate": str(date.strftime('%m/%d/%Y')), ... } Due to the fact that date.strftime returns Any type, for my type hinting and autocomplete to work I either need to pass it to the str function or typing.cast(str, date). It would be nice if I could just write "birthDate": date.strftime(r'%m/%d/%Y') as str, like in C#. It's shorter, (in my opinion) more readable, and avoids having to unnecessarily call a constructor or import typing.cast. It's important to note that this would be syntactic sugar for typing.cast— it wouldn't call any constructor or affect program state, just increase the power of the type hinting system. Will Bradley
