Of course. They example was deliberately chosen to make F#'s BigInt library look as bad as possible. > I would expect .NET code to smoke stock > (non-Psycoed) Python in this benchmark. Probably. It just so happens that the example chosen is typical of _my_ number theory research and I was toying with the idea of converting my Collatz Conjecture function library to F#. And that would take a lot of work since F# doesn't have anywhere near the functionality of gmpy. There isn't even a BigInt.mod function for cryin' out loud, let alone stuff like GCD or modular inverse, critical to my research. Sure, I could write my own Extended Euclidean Algorithm, but now that I now that F# is just a Volkswagen with a fiberglass shell that looks like a Ferrari, there isn't much point, eh? And don't even get me started about the stupid stuff, like having TWO different type of Big Rationals. One's more efficient than the other, they say. So why two? The less efficient one has functions not implemented in the other. And F# is strongly typed, so you can't use BigRational methods with BigNum types. And they have all sorts of conversion methods for to/from ints, strings, bigints, etc. Guess which conversions they don't have? BigRational <-> BigNum, of course. MAybe I'll check it out again in the future after it has gone through several revisions. -- http://mail.python.org/mailman/listinfo/python-list
