No, I see no need to smuggle the full tower in by the back door.
What I'd like to see is the Chicken core (FFI and all) migrated from
pure fixnum+flonum to fixnum+flonum+bignum, providing unlimited exact
integers plus IEEE double floats. If even tiny Chibi Scheme can do
that,
so can Chicken. In fact, Chibi's routines are BSD-licensed and would
be easy to adapt to Chicken.
integer flonum limit of +-9007199254740992 should be good for awhile.
Sure, in contexts where people feel comfortable using inexact numbers.
But having to use them for file positions is a kludge.
While not "comfortable" with 10.0 as a file position is understandable
does anyone really use '(exact? some-filpos)'?
I am not defending the lack of bignums in Chicken. Just trying to
understand the need.

Most languages are dramatically underdescribed, and at least one is
dramatically overdescribed. Still other languages are simultaneously
overdescribed and underdescribed. Welsh pertains to the third
category.
