Do enlighten me how to use intrusive reference counting in D. I am quite

Andrei and I are working on it. As he's expressed elsewhere, the idea is
to maintain the reference count in memory that is outside the type
system. It's meant to work hand-in-glove with the storage allocator.
First of all, it sounds like you envision that everyone will solely be
using the D supplied allocators, and no one will be writing their own.
That's not my vision of how a system programming language is used. In
fact, I have seen very few large scale projects where a custom allocator
was not used.
Either way, prefixing data to a structure is not what "intrusive" means.
But even if this turns out to be an adequate replacement for all the
cases in which I'd want to use intrusive reference counting in C++
(unlikely), that only works for my first example, not my second one.
