I enjoy writing statically type-checked Python (previously with Mypy, now Pyright) but it's always in my mind that in absolute terms this is an absurd situation that the language has worked itself into. Namely that all the effort you put into writing well-typed code, while beneficial for correctness thanks to said sidecar dev tooling, is thrown out the window and not used for optimisation by CPython.
