Thanks Remi!

Yes, inner classes seem to be the necessary evil when you need to
generate "just" a single method. Our saving grace here is that we only
need to do this for one "shape" of concat, and there are seem to be only
handful in a given application. I agree that doing that purely on MHs
would be cleaner, but I have my doubts about the performance of it.
Let's see!
