what's wrong with:

#4
    for path in sys.path:
        if isinstance(path, types.StringTypes):
            do_standard_import(...)
        else:
            path.do_import(...)

after all, everyone knows how the path works, and everyone knows how
to manipulate sys.path inside a Python program.

(for PIL and other plug-in architectures, a "path.get_list_of_modules"
method would also be nice).
