Common Lisp supports optional type declarations also without
CLOS/multimethod mechanism. Type declarations are used to improve
performance of the compiled code.

Guido has said (Nokia "Python for S60" workshop in June) that Python
will also have such declarations at some point in time.

Multimethods (as a runtime mechanism) can be used in Python too,
multiple solutions have been presented on the net.
