  from your problem description, it does not seem excessively rational to
  want to store fixnums.  I'd just go ahead and store double-floats.

  it is indeed a useful facility, but it helps a lot to be able to access
  the declarations and (other) type information (inferences) in the
  environment it is expanded.
