Thanks for the suggestion! I wondered about this before, but the idea
fizzled through a combination of doubt about how much performance gain
would be involved and the impression that using __slots__ would preclude
creation of new attributes on basic NumArrays.
Seeing real information about the performance motivates me to take a
closer look, so thanks. I think placing the "no new attributes without
subclassing" restriction on NumArrays is probably worth the gains and
will check into it.
This day is getting better and better,
