Ooops, my bad, I could have looked that up.

OK, so you think that is the difference? Do you think we should do that?
It is quite easy to add. Is there a performance issue? In which case
should we threshold on the size of the input arrays? Or give the choice
whether to add the filter or not through a keyword argument?

I am all for improving mlab :).
