: Not necessarily true.  I've written lots and lots of Lisp programs, and

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.
