Hello Martin,

Thanks for posting this.  We had already been discussing it earlier
today in #chicken.  I had another look at the code but I can't really
find any obvious inefficiencies.  It is indeed a bit faster with
CHICKEN 5, but not by much.

Of course, Guile is "cheating" by using GMP.  If I compare it to another
Scheme which has its own bignum implementation like Gauche, we perform
about the same.  It's interesting that sbcl is doing so well.  Maybe I'm
overlooking something seemingly minor but important?

Cheers,
Peter
