Good.

In this case, you run into the problem of lifetime management. Unless you use
globals, how do you guarantee that once all users of the array are done with
it, the array is deleted? The array must be deleted from either the python
side (via numpy) or from the C++ side (by yourself). Handling this problem is
the cause for much of my code (which may still be too heavyweight for you).
