In Python, you have to reimplement __repr__ for every class whereas in Haskell you use deriving Show. This has nothing to do with static vs dynamic.

Python's `__dict__` is probably a better example of duplicating Haskell's `derive Show` behavior.

Why? __repr__ (or __str__) is pretty much the "show" method, in Python. It isn't derivable (or rather, the default derivable one is useless), though.
