"works" is not sufficient. Among C++ people the first reaction to GC
usually is: -"impossible" for one technical reason or other. Not unlike
what I experienced here. In practice it works. Unused memory is
reclaimed and reused, heapsize will not grow and it is fast. It works.
Currently this has to be qualified with "Using compiler A, version B and
library C version D" and that is a problem.
With standard sanction the potential problems you and others (optimizer
tricks that might trip off the collector) would also be under control.
If there is GC it is controlled by the same people that control the
optimizer. With sanctioned GC there would be restrictions on what
optimizer tricks would be allowed.
To be useful in a world (C++/Ada) where GC is optional one needs *some*
language support. At least enough to portably determine if GC is
available at compiletime. A progam designed for GC should not compile on
a compiler that doesn't support GC. C++ (currently) fails here, how
about Ada?
Also, using GC would be "allright" if it was part of the language, even
if optional.
