And a Question to Doug Gregor Does ConceptGCC support decltype and auto? Please 
note: this is Not a feature request, just a simple question! :-)

The point of that is that I would love to try porting my Quan library to use 
Concepts, but for Quan, the one feature that would be the 'killer compiler' 
application is decltype and auto. Quan would be a nice looking library with the 
combination of Concepts and those features. In reality I don't know where I 
would find the time to do that port though.

I know that gcc has problems with typeof and Boost.Typeof, in return types, so 
OTOH I guess this functionality may be problematic?

Of course if I really want it, then I guess I ought to try sorting it out myself 
though shouldnt I?  :-)
