Perhaps it would be useful to distinguish between what might be called "read-only" introspection, and more powerful forms of introspection.
Usually it doesn't do any harm to be able to find out things like what class an object belongs to and what methods it supports, so perhaps these kinds of introspections don't need to be restricted by default.
A serious flaw with this particular point is that Python does not separate the identity of a class from the power to create instances of that class. Having access to a particular instance should certainly not allow one to ask it for its class, and then instantiate the class with arbitrary constructor arguments. -- ?!ng
