There is nothing to prevent an implementation from doing so. My sample implementation of SRFI 128 reduces lists, vectors, and strings mod 2^20 rather than taking the risk of overflowing into a flonum on Scheme systems (such as plain Chicken) where that is possible. -- John Cowan http://www.ccil.org/~cowan email@example.com But that, he realized, was a foolish thought; as no one knew better than he that the Wall had no other side. --Arthur C.
