But the kinds of folks who have tolerated the bug which Dan Wienreb so
gloriously announced are not entirely stupid. There is a market, at
least amongst some systems programmers who use lisp, to get the kind of
"last-bit tweaking" performance that a stack-allocated &rest list would
afford. Lucid's product will shortly be giving the user access to some
of the underlying primitives which permit dynamic-extent consing (the
3600's "stack list" consing is one such example).
In fact, we use stack allocated &REST lists exclusively. We tried using heap
allocated &REST lists and found that it significantly impaired the performance of at
least one large system. I think lisp vendors should be encouraged to provide this
sort of feature.
