At least for 'bigger' bignums, gmp can be expected to be _way_ faster than
guiles implementation. The gmp folks have implemented their core routines
in assembly language on a lot of major computing platforms. Further,
they use sophisticated algorithms to get the best possible performance.
However, for bignums that consist of just a few words, there may be a
performance penalty.
