Interesting... So you're claiming that humans have powers of deduction 
beyond what computers possess? ;-)

Note that no theorum claims that a computer can never tell whether a 
given pair of functions are equivilent. The theorum is that a computer 
will never be able to tell for *every possible* pair of functions, 
that's all.
