Don't forget the case where the copy semantics may actually provide an
*improvement* in performance by allowing a potentially large array to

This Pull Request looks like a good idea to me as well.

I recently had need of tracing numpy data allocation/deallocation. I
was unable to find a simple way to do so, and so ended up putting the
code below into ndarraytypes.h to allow me to trace allocations. A
key part is that this jumps back into python, so I can inspect the
stack and find out where

Hi,
I am getting into troubles when using numpy.testing with coverage. A
minimal example package is atached to this email. Unpack and run:
$ python -c "import mypackage; mypackage.test(verbose=10,coverage=False)"

All,
I’ve been fairly quiet on the various missing/masked values proposals,
sorry about that. I figured I would take the opportunity of Travis O.’s
deadline of Wed. 16th to put some aspects of numpy.ma in a semi-historical,
semi-personal perspective. Apologies in advance if I misrepresent some
