Except the more I think about it, the more I suspect that this would in 
fact require restarts a la common lisp.  Why doesn't scheme (except MIT 
scheme) have restarts, anyway?  They are the prettiest error handling 
mechanism I've ever heard of.

PS: just found R5.91RS, which does seem to have a sort of a minimal 
restart feature.  That does look better.
