I concur with Alex; people who need numeric performance are no strangers
to special compiler flags, and improving the correctness and ease of use
of the general case must take priority.

Also, with it all integrated and bugs kicked out, we will be free to
look at micro-optimisations of the code in future; I'm assuming we may
be able to do something with range analysis to prove the fixnuminess of
some numbers, and specialisation on fixnums in future.
