Please read either Joe Marshall's magnificent defense of what and how to standardize, or else my rather limping remarks to much the same effect in reply to David van Horn. > I don't see the goal of Thing One > as being the lowest set of features through which all other features might > be implemented. Neither do I.

It's the other way about. If a set of useful procedures is large and easily implemented (like SRFI-1), we can safely leave it out. > > [SRFI 8] receive > > Why would we need to do this? This is easy to implement. Assoc is easy to implement. List is easy to implement. We have them because they're expected and useful. So is receive.

If you believe in force and delay, this fixes a bug around force-delay combination vs. tail recursion, redefining force and delay in the process. > I want any module system introduced in core Scheme to be absolutely > compatible with a larger module system used as the standard everywhere. So do I. I'm not sure, though, exactly what that means. -- "The serene chaos that is Courage, and the phenomenon [email protected] of Unopened Consciousness have been known to the John Cowan Great World eons longer than Extaboulism."
