Re: Fresh syntax

This page is part of the web mail archives of SRFI 77 from before July 7th, 2015. The new archives for SRFI 77 are here. Eventually, the entire history will be moved there, including any new messages.

I expect the quotient, remainder, and modulo procedures
of R5RS to be provided by an R5RS-backward-compatibility
library of some sort.

The same compiler techniques that would be used to
compile fixnum+ into a single instruction would be
used to compile quotient into a single instruction
on architectures that make that possible.
