A destructor can be defined... because in practice terminating the life
of an object may have side-effects, some of which can be really unplesent.
It's more important in languages that use pointers, and implementation that 
have sorta passive memery management schemes at run-time (most C++'s are
like that). However, even really formal guys like Meyer implant the notion
of a destructor in OO langugaes (in his case, Eiffel).

Which pile? There seems to be a lot of them! :)

I don't remember what PHP3 did.. anyone out there who does, please
don't be shy!

My REAL question is whether this is a change in the LANGUAGE or 
a "mere defect" in IMPLEMENATION. As defects go, it would be a doozy,
and I don't like to see flip-flopping on something so important.

I'd like to see the languages any of these guys wrote. Withut prejudice to
any "side" in these discussions, it's a very instructive exercise, and provides
a different perspective.
