Good! so for numarray-->Numeric we have really good performance now.

I'm not sure what are you saying here. You mean that in CVS there is
already code for Numeric-->numarray that does not degenerate to
fromlist() anymore? If this is the case, it's great news, of course.
I'll try it as soon as I can.

Thanks,
