There are tons of other examples of this if one thinks "mini-language
interpretation".  For example, a program that asks the user to enter a simple
mathematical function and plots its graph would be seriously faster in
Python+Psyco than in ANSI C.  And if you feel that using Python's compile() is
cheating, then write a simple parser and interpreter for the user expressions
(just as you would in C) and it could run faster than C if Psyco were advanced
enough to specialize it correctly.
