Yes, I forgot I about that one (sorry), because I considered
it minor.  I had already fixed that locally, but didn't check
it in because now you can't use dune-disc with 1.0 anymore.
Was your last dune-disc commit deliberate?

By the way, can we have email commit notification for
dune-disc back?  Thank you!

Well, obviously, the best thing to do is to reimplement all the nice
std::array features in Dune::array.  However that looks like a lot of
work to me and I am still trying to make myself believe that it is
not necessary... doesn't really work, though.
