PS, just as a clarification of my earlier message: while it is quite
difficult to write practical programs that do what you want and only
require what R5 provides (dare I say "impossible"?), it is not nearly
as hard (altho still difficult) to write programs that do what you
want and work in some small N number of implementations.
