Better late than never :)

FB people have great experience with introducing typing into weakly typed languages (e.g. PHP vs Hack). So I actually started using pyre-check in place of mypy. The tool is really great and fast. I also like pysa quite a lot.

Pyright only came into focus because it was best Python LSP implementation for NeoVim, and it is also the default for helix-editor which I play with. It's also nice that I could suggest pyright for some younger colleagues using VisualStudio Code (with strict mode enabled of course).

P.S. I'm also using other interesting tools and libraries from FB (Instagram) like libcst [1] or fixit [2]
