I don't know what Walter's current plans are for what any built-in
ref-counting solution would look like, but it's my understanding that
whatever he was working on was put on hold, because he needed something like
DIP 1000 in order to make it work with @safe - which is what then triggered
his working on DIP 1000 like he has been. So, presumably, at some point
after DIP 1000 is complete and ready, he'll work on the ref-counting stuff
again. So, while we may very well get it, I expect that it will be a while.
DIP1000 is needed to make ref counting memory safe.
Andrei is working on ref counting, and he's concluded that copy constructors are
a key feature to make them work. Postblits are, sadly, a great idea that are
just a failure.
Hence, dip1000 and copy constructors (Razvan is working on that) are key
technologies.
