Chuck, did you just hijack the thread ;) ?
To replace thiings in context: a few weeks ago, we had a global flag in numpy.ma that prevented warnings to be printed. Now, the warnings are handled in a case-by-case basis in the numy.ma functions. The problem is that when a numpy function is called on a masked array instead of its numpy.ma equivalent, the warnings are not trapped (that's what happen in the tests). In order to trap them, I'll have to use a new approach (something like __array_prepare__), which is not necessarily difficult but not trivial either. I should have plenty of free time in the next weeks. I'm afraid that won't be on time for the 2.0 release, though, sorry.
