I have just sent a new draft of SRFI 38 in to schemers.org. It's
likely to be up sometime in the next few days, and I'd like for folks
to have a look at it.
Al* petrofsky, would you like a co-author credit on this one? the
code of the actual implementation is 99%+ yours after all, and that
was surely the toughest part of it. The stuff I did was pretty easy.
As far as I know, the new draft (revised 30 January) is ready to go
into final state.
