Hooking exceptions outside of call stack

Wow! I've never seen that, before. Is there documentation for `type(n)(...)`
somewhere? I did find a very useful "Decorator for Binding Constants, by
Raymond Hettinger", that uses this technique.

The calls are made from embedded classes that are constructed on the fly:

  class a(object): ...
    class b(object): ...
       class c(object): ...

for `a.b[c]=1`, a.__getattr__('b') is called but 'c' need to be resolved as
an object before a.b.__getitem__(c) is called. Could a.b.__init__ set
globals so that 'c' gets resolved? Is this global namespace the same as the
`globals()` namespace?
