I suggest that bignums _not_ be part of the core language, but built
on top of the core language _in Lisp_ using the appropriate primitives
(fixnum+fixnum -> fixnum + fixnum(carry)), etc.
This and a number of suggestions are made in

Perhaps, due to the interest in LispOS, it is time to reread this
