Yeah. You don't want to try reading the GCC message for a std::cout error. It's like 80 lines of different template overloads of the '<<' operator.

Better template constraint errors are on our Agenda for later this year.

But the more powerful the generics are, the harder it is to make good messages, that's what I'm saying. And that compared to the power of our metaprogramming, the messages aren't that bad after all.

But I agree D can, and I believe will, imporove there regardless.
