Not supporting plugins for a type checker to me is a plus. It’s quite frustrating that some Python projects only typecheck if you have plugins. That is a major source of frustration.
python packages that do a lot of metaprot can only be properly type checked if you replicate that metaprogramming at the type level. e.g. if dataclasses were not part of the standard library they would need a plug-in to be handled correctly.
Yes, this is it. You can usually find some discounted or free way to get most books, but I had classes where you literally submitted homework through the same system you accessed the book through, and it was like $150.
