Re: Loop optimization

[Michael Ellis]

Thanks for the education, Andy, and congrats again on the guile
compiler implementation.  Your version handily outperforms the fastest
python implementation I know.

for i in xrange (10000000):
    pass
print i

real    0m0.641s
user    0m0.625s
sys     0m0.012s


(let loop ((i 0))
   (if (<= 10000000 i)
       (begin (display i) (newline))
       (loop (1+ i))))


real    0m0.495s
user    0m0.465s
sys     0m0.010s

Cheers,
Mike
