Let's just say that this didn't happen in any of the German math classes I ever took, school or uni.

And that's how it was always taught to me. This is, of course, a different question from what a library should implement ... though I must say if I were interested in NaNs at all for a given problem, I'd be disappointed by any such library that didn't return a NaN for 0^0, and of any language standard saying so - I'd certainly consider a result of 1 wrong in the general case.
