What would your intuition say? Should this be equivalent to dict(locals()) ? That example is so elegant it makes me want to cry. And not just because you shadowed the vars() builtin wink

It gets funnier with nested loops. Or scarier. I've lost the ability to distinguish those two.

def test(): spam = 1 ham = 2 vars = [key1+key2 for key1 in locals() for key2 in locals()] return vars

Wanna guess what that's gonna return?
