I dont' think the ufunc is the right place for this. Perhaps sorting
can be viewed however as a "general function" which I'd like to add.
Maybe, in that case the ufunc could be a special case of the "general
function" concept. But, that is the direction I would expect the
discussion to go.
The ufunc object is a very particular kind of thing. The 1-d inner
loop signature is a key part of it, but there is more to it than that.
I don't see how the sorting function can be pushed into this concept.
But, there is a case to be made for perhaps figuring out how to merge
the data-type functions and the ufuncs into one idea that allows for
better code re-use.
