I’m trying to use them more and they are helpful but they can be tedious because now I sometimes have to remember to import the right typing modules and I’m not very comfortable with typed sequences or union types. Anyone have a good cheat sheet or reference? I’m adding them to code I’m refactoring and it definitely helps there. Instead of a random named variable I can now get completions for the thing I’m working on and dependencies are a lot easier to see and use.
