You could create a matrix class with an add method so that the rest
of your code wouldn't see the loops. This sort of trick is one of
the points of OOP. Still there need to be loops somewhere. Even
languages like APL that hide the loops from the programmer still
generate it in the assembly code.

Poorly, at least for now.
