Decent looking mailing list esque service, with a free plan but with paid plans as well, so presumably not AS likely to 'exit'. GH integration, etc. Also has a ton of shit I will never use but eh.

API Reference — more-itertools 3.0.0 documentation

lmacken/pyrasite: Inject code into running Python processes
