C++ completely decouples allocation, construction, destruction, and
deallocation. You can call operator new(), constructors, destructors,
and operator delete() directly.
And by the way, the reason I am interested in C++ is that the standard
is coming back around to the point in the ISO cycle where we can start
to consider extensions, including garbage collection. The Boehm
collector, the Great Circle collector, and various "smart pointer"
classes are some of the existing practice we have to start with.
The existing practice in java and Limbo is arguably relevant as well.

I'll think on these, thanks.
