Also (this is an absolutely uninformative and uninformed remark, I
know) I hope you/we will think these matters over very carefully,
before possibly throwing a baby out with the bathing water. Some of
the mysteries of S are probably better categorized as design bugs, and
in contrast Lisp-dialects have been subjected to a long history of
analysis by computer scientists in all the critical issues of memory
handling, scoping rules, optimizability, compilability, etc.
A little divergence between the two languages is not really critical,
we already have it in the scoping rules, and as long as the internal
logic is OK, I don't think that the porting issues are all that bad.
