It's doesn't match the implementation, though (which I think is bad,
because I think the implementation is simpler than what you describe).

This implies that functions know about what it means to be a
classmethod, or to be synchronized.  They don't -- classmethod knows how
to take a function and create a classmethod object, synchronized knows
how to take a function and wrap it with locks.  The original function is
no longer accessible.
