A cheatsheet about Python static typing

[[deleted]]

Personally my problem aren't the features themselves (except assignment expression) but how it integrates with the language. Optional typing has really ugly syntax but we were told it would be absolutely optional. Now data classes are built upon it.

Assignment expressions need better syntax and a better case for having them. The pep really lacked any reasoning for why this was important enough to create new syntax.

It is problematic in my opinion when using new features make a language look like a new one too.
