[pro] What was wrong with environments as in CLTL2 pp. 207-214?

[Jean-Claude Beaudoin]

Dear all,

I am currently implementing the environments interface described
in section 8.5 of CLTL2 (pp. 207-214) for MKCL.  It feels like a
very natural extension of what was already part of the code of the
Lisp-to-C compiler MKCL inherited. It feels so natural in fact
that I cannot figure out why that feature has been pulled out
of the final ANSI CL specification. [And I have a hell of time
standing all those (declare (ignore env)) sprinkled all over the
MKCL source code.]

I think that some of you reading this list were there, part of
the action, during those standardization days. Maybe you could
shed some light on what was wrong with this part of the spec
and motivated its removal.

Cheers,

Jean-Claude Beaudoin
