Is this really true for C++? I believe one of the reasons for providing
constructors and destructors was to supply the programmer with explicit
control over initialization and finalization, so that memory-safe non-
leaky implementations could be constructed. I've never heard anybody
claim before that without any effort on the programmer's part, garbage
collection is automatically taken care of in C++ (I've heard of it
being taken care of automatically in LISP, and not well...). Sure, on
a UNIX box one can semi-safely ignore garbage issues, but that's just
because the problem is swept under the carpet of job control--at
some level the kernel is still having to deal with garbage collection,
memory fragmentation, etc.
