Most probably. I know that the last time I looked into it (which was right before the 1.29 release) there were some subtleties which I wasn't ready to deal with, not the least because the timing was wrong as well. Don't get me wrong, I would love to see it fixed, just not in 1.30.0. > But there is another point: AFAIK the GCC does support partial > specialization, right?

Sure. By all means it would be appreciated if someone contributed a comprehensive fix which would close the issue. > > If it was easy enough it would be fixed long before the release.

Okay, that's good to hear :), sorry if I overreacted a bit. 1.30.0 preparation period has lasted long enough for some of us to want it to be over already.
