Will the concepts branch be discontinued?
I hope not. Concepts will be "finished" and re-added to C++, and it
would be immensely helpful in that effort if there were a version of
g++ with stronger Concepts support than ConceptGCC had.

We need a gcc branch for concepts. One of the major complaints on
concepts and one of the major contributors to its being dropped is that
there is no implementation experience. There was no implementation of
sufficient quality and availability to give compiler developers
confidence and point to wrinkles in the definition and users time to
learn and play. It will take a good couple of years to get one working.
That leaves open the question of whether the ConceptGCC branch is the
one. I just don't know. Maybe someone should start over. I think aim
for simplicity. That was another issue I think:
