Optional typing is definitely coming. As eeZi pointed out, and I've been following this in the mailing list also. https://www.python.org/dev/peps/pep-0484/ https://www.python.org/dev/peps/pep-0484/ Guido is pushing to standardize mypy as static analysis for py3k, but it is taking so damned long, meanwhile something like TypeScript is already superb with it's compiler service architecture providing great tooling for all kinds of editors & IDE. PEP484 is simply too little, to get good tooling it requires compiler service (API for IDEs), and we are long way from that.
