I really think that this should be a separate module (right now we call
it tentatively "boost.numpy"). It introduces additional dependencies
which not all boost.python users may be interested in.

And yes, I had planned that we could address enough of the remaining
issues to be able to submit boost.numpy for formal review within the
next couple of months, i.e. ideally even before the end of this year.

FWIW,
