Python doesn't really have "interceptor methods". In fact, there
aren't any magic methods that are called specifically on method
calling -- only attribute access (well, except for __call__, which
happens when you do obj(), but that's a separate step in the process).
__getattribute__(self, name) --> Always called on attribute access.
__getattr__(self, name) --> Called after looking up the attribute
fails by regular means.
__get__(self, obj, type=None) --> Called on an object when that object
is accessed as an attribute of
another object. f34r this. :-)
Any of which, of course, can return methods. :-) btw, remember how
Python creates `bound methods' when you access a method through an
instance? It's implemented with (the C equivalent of) __get__ (As of
Python 2.2). More information related to that (and other useful
information in general) is here:
http://www.python.org/2.2.2/descrintro.html.
Btw, these all have `set' and `del' friends, but they don't always
perfectly match up with the `get's... I'll get back to you on that.
