Here's a good function header given the following:
I wrote the below code

    def decorator(func):
        return func
    arg0 = ((len(args) and args[0]) or None)
    if (callable(arg0) or (type(arg0) in (classmethod, staticmethod))):
        return decorator(arg0)
    else:
        return decorator

What's a good function header?
