The Lisp i programmed in (symbolics) had a really nice feature --
allocation to *named* areas of memory. You could allocate
objects with differing life spans in different areas and then
(at the appropriate time), wipe a whole named area and start over
without having to destroy the objects individually. Very fast
and easy to control. I'd like to see a feature like that in C++
and ADA.
