I'm going to assume pylint or pyflakes would throw too many warnings on the stdlib, but would it be worth someone's time to write a simple unused import checker to run over the stdlib on occasion? I bet even one that did nothing more than a regex search for matched import statements would be good enough.

Zope 3 has an import checker that uses the compiler package and AST tree to check for unused imports. It seems like a better approach than a simple regex search.

The importorder tool uses the tokenizer module to order import statements.

Both are written by Jim Fulton.
