Ah well then I guess I'll just take your advice then. Those procedures seem like a nice way to create a brand new "base language" to program in, though. e.g. I could write a completely object-oriented Scheme based on an add-on OO library and the predefined non-oo procedures.

Ah so you're planning on implementing R6RS. I can't remember what was in the draft specification, but it seemed the R6RS module system would be very much "static". No top-level defines and such... I hope this doesn't make things difficult for people like me who would like to program interactively, rather than edit-compile-run a bunch of text files. But perhaps that discussion would be better carried out in the r6rs list...
