One issue with that idea is that staticmethod, classmethod can actually 
arbitrary objects, not only Python functions. In fact, even this object 
can be created:

 >>> staticmethod(42)
<staticmethod object at 0x7f74ab9c55f8>

So in that sense, they behave more like "method" which can also wrap 
arbitrary callables (in this case, callability is checked). So I'm 
vaguely thinking of putting "method", "staticmethod" and "classmethod" 
on top of a common base class for things wrapping callables.
