Java? What about BASIC? Good old Microsoft BASIC (for the Z80 -- remember
those?), that fitted into 8K ROM, had GC, as did a variety of other BASICs
(some of them even tinier). And they were pretty popular for a period. I
think your statement might upset a lot of LISP enthusiasts, too. (Not to
mention Smalltalk, Prolog, xBASE, and probably many others ;-)

Maybe not in so many words, but actually there are a lot of people who claim
that a static typing system causes more trouble than it is worth. I am on
this side of that particular fence, but I see their point (e.g. it can
reduce the size of the source code by several times, which in itself, it
could be claimed, improves readability).

Actually, I think, with a bit of care, it is possible to design a (perfectly
good) GC system that defends quite effectively against the worst effects of
'damage'.
I think, in the end, I will take the advice of both Brian and Bob, and
simply implement GC myself (in my own compiler which I'm writing for AdaOS).
I just thought it would be preferable to have a widely agreed framework
within which to design it first.
