Thanks Doug, impressive. In my opinion, everything considered - in 
particular the fact that variadic templates do *not* introduce any new 
keyword - it would be great if we could apply your patch (and the 
corresponding library changes, of course) as soon as possible, early 
Stage 1 of the next release cycle, I think.

At the same time, I (still) believe we badly need a global strategy for 
the C++0x features, for those features adding keywords, 
incompatibilities, and all the others: as noticed by Richard G in 
private conversation, probably the transition could be managed similarly 
to that to C99, only I'm not sure about the current time frame, when 
only a draft of C++0x exists and, I would say, many of the most 
anticipated features are not there yet. What about adding something 
about that process in the wiki section about gcc4.3 (by the way, I 
noticed that variadic templates are already there, good)??

Thanks again,
Paolo.
