Well, I used ConceptGCC many times and it works quite well now.  The 
fundamental concepts on the GLAS list, like ring and group, are 
implemented with concepts now and compiled with ConceptGCC. I published 
the results as technical report:

http://www.cs.indiana.edu/cgi-bin/techreports/TRNNN.cgi?trnum=TR638

There is amongst others an example to compute the power function with 
regard to an arbitrary binary function. There are different algorithms 
for magma, semi-group, monoid and groups. The concept compiler 
dispatches to the most appropriate.

In another paper still pending I did performance experiments and it 
showed that the performance is the same as with gcc without concepts.

There were occasionally some minor problems with ConceptGCC but Doug 
fixed most of them in the meantime.  That said, the compiler is not in 
perfect production mode yet but it is already extremely useful for 
working with concepts.

Cheers,
Peter
