Also, I hope we'll be able to allow allocators to define
Pointer(T), Ref(T) etc. that supplant replacements for the
built-in notions of pointer, reference etc. Then, user code
that uses these notions instead of the built-in ones will be
guaranteed some nice properties (e.g. automatic reference
counting). Unfortunately I don't see a way for an allocator to
enforce that its users don't do illegal things such as escaping
addresses etc. So it would be a discipline-backed scheme.
Notable beneficiaries will be containers.
It will be fun without tail const.
The global GC does offer manual deallocation. It's the presence
of collect() that indicates tracing abilities. If
deallocateAll() is present, user code must assume it will be
called during destruction.
It doesn't make any sens at this level. These allocator do not
know what a pointer is. And can't be @safe if they do know.
