2to3 gives a warning while converting portage codebase using map¹ fix:
RefactoringTool: Warnings/messages while refactoring:
RefactoringTool: ### In file ./pym/portage/dbapi/porttree.py ###
RefactoringTool: Line 266: You should use a for loop here

This is a valid warning because map() will change in py3k. Read the docstring of
fix_map.py for more information.
