all this to say i broke some code

hundreds-father-404 · Answer

yeah have to use ` ` for `cast` because it s not a type hint

hundreds-father-404 · Answer

It s clunky but I personally prefer `cast dict str str foo ` to `Dict str str ` w an import

`from future import annotations`

hundreds-father-404 · Answer

not for `cast` which is a normal fucntion call rather than an annotation

bitter-ability-32190 · Answer

Ah of course

so um regarding the code i broke `build support bin generate docs py` should i constrain that to 3 9 or downgrade the syntax it made it through because `mypy` is happy with either

hundreds-father-404 · Answer

I m fine with constraining to 3 9 as an M1 user But not sure if all Pants devs have that And then it will result in our linters partitioning maybe that dogfooding is good
