This looks ugly to me. I do have top level functions that would use
decorators because those functions will be put into a class as
classmethods and this class will be put into sys.modules instead of
the original module. Replacing

def foo(cls):
    ...
foo = classmethod(foo)

with

if True:
    [classmethod]
    def foo(cls):
       ...

doesn't look that attractive to me.
