Assignment operators definitely should return lvalues normally. I don't know why deadalnix would think otherwise. It's pretty much the norm in C++, and I see no reason for it to be different in D. No, it doesn't work for all types, but in the general case, it should. However, given the current state of AAs and the fact that their implementation pretty much needs to be completely redone, I'm not sure how good an idea it would be to make this work right now. Maybe it wouldn't be a big deal, and maybe it would be a very bad idea. It certainly wouldn't hurt to open an enhancement request though: http://d.puremagic.com/issues At minimum, I would think that in the long run, we would want what you're trying to do to work. - Jonathan M Davis
