[ Related to discussions we had about the need for fixnump and such
  things.  ]

I think we should try to try and avoid exposing the notion of "fixnum",
so here for instance, we should likely just accept any integer plus
document that only the lowest N bits are used where N is
platform-dependent (and it could even be different from the number of
bits in fixnums, in case we want to use the full 32bit/64bit range of
ints for hashes).
