Perl code 37 times quickly than Python code??

Here an idea of what python jit compiler can do (psyco)

computed by Psyco in 0.402314260611 seconds
Python got the same result in 1.72031193909 seconds, Psyco is 4.28
times faster
(and 4.4 when *warm*)

As with all benchmarks, this is a useless number, but shows what
wonders a jit compiler may do for python.
