How is this any better than:

    import my_really_long_named_module as m
    m.foo(a, b, c)
?

For avoiding import statements, you could write something
like this:

    class ModuleGetter:
        def __getattr__(self,name):
            if name.startswith('__'):
                raise AttributeError
                    return __import__(name)
    module = ModuleGetter()

And now you can do without the imports:
    module.mymodule.foo(a, b, c)
    module.os.chmod(blah, blah)
    x = module.re.compile('[a-z]')
