[MATRIX-SIG] Making pseudo-ufuncs?

Nothing I can think of.

You could try to check for general sequence objects, and then your
functions would even work in lists. But the tricky part is getting
a return value in the same object type. I am not sure this is worth
the effort.

I'd define another class for binary functions and assign the
reduce/accumulate/outer version to an appropriate attribute. Then
you could use the same syntax as with ufuncs.
