That makes sense to me. As far as I know, asmatrix() defaults to calling the constructor if it can't snarf the memory of the object being passed in. So, go on, shoot Ed and me down! :-)

I can anticipate one problem: the Pirates will want their three-letter abbreviation for asarray.

Will functions like rand and eye always return arrays? Or will there be a day when you can tell numpy that you are working with matrices and then it will return matrices when you call rand, eye, etc?
