JF> Note that signatures will *not* be available as attributes of
JF> the interface. For example:
| class FooInterface(Interface):
| def spam(a, b):
| "blah blah blah :)"
JF> FooInterface.spam # raises an attribute error
Why? Doesn't it make sense for introspection purposes to have access
to the methods defined in an interface through the interface object?
