Yes, I guess it is. But the project doesn't seem very active...

Yes, I guess you're right. There is no point in adding this sort of
thing to numarray. My motivation for using numarray in my
implementations was simply that it would mean that the necessery tools
would be (or might be in the future ;) available in the standard

Well... I do sort of mind... I'm a bit wary of using unmaintained
software. Not that I would never do it or anything... But I think it
would be a bonus to use stuff that is being actively maintained and
developed. But I guess I'll take another look at it.

(Any idea where the "kj" prefix comes from, by the way?)
