Hi David, Fijal. I'll reply to this earlier post as the overnight
discussion doesn't seem to have a good place to add this.

Someone else (I can't find a name) posted this nice summary:
which mostly echoes my position.

Does anyone have a guestimate of the size of the active numpy user
community minus the scipy/extensions community. I.e. the size of the
community that might benefit from pypy-numpy (excluding those that use
scipy etc who couldn't benefit for a [long] while)?

At EuroSciPy it felt as though many people used numpy+scipy (noting
that it was a scipy conference). At EuroPython there were a number of
talks that used numpy but mostly they used other C or extension
components (e.g. pyCUDA, Theano, visualisation tools).
