I hope to - rather I have - introduced a statement of fact about a
particular problem domain.  For instance, DirectX Graphics only takes 4-byte
floats.  I have no interest in using 8-byte doubles for my game code.  Aside
from API compatibility issues, it's piggish in terms of both space and time.

It's not abuse of the original poster.  He didn't promise me anything about
my problem domain.  If you want to say I'm abusing the language authors,
fine.  I see no other way to criticize a language.  I think you're being too
sensitive.

What I'd like to know:
- does Numeric Python remedy this deficiency?
- if not, will this deficiency likely ever be remedied?  when?
