I don't think either reach the real wtfs of their language. id() does some weird things with string interring, javascript coerces cross-type arithmetic into weird nonsense instead of throwing a type error. Whatever, neither of these come up in the real world.

Builds so messy that you need to resort to venv, every second DOM API being someFunc(thirdMostImportantArgument, { mostImportantArgument: val }), these are the real wtfs.
