Nice work. However, I would say that in an OO context there's a case
for walking the @ISA Tree to find out all the methods that the class
will respond to, say $object->all_methods, after all, in a complex
class hierarchy there may be classes that implement only one or two
methods that are distinct from the methods of their parent class.
Actually, I'd like to see something similar done to Universal::can
(though Interface polymorphism may make this less important...)
