I recommend not to use fixnum mode, and to use fixnum-specific
operators instead. It can happen too easily that a library procedure
returns inexact results (for example for very large numbers that
exceed fixnum range).

Apologies for the ruthless cleaning up over the holidays, but I think
it is better go through this sooner than later.
