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:
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.
