Extending arithmetic

Matrices aren't as straightforward an extension.  You're no longer 
dealing with a fundamental type--a tuple--but nested tuples in a 
particular format.  It could get messy quickly.

I wondered about that as well.  You could certainly do it, but tuples 
are more self-contained than lists.  You can't tell up front if two 
lists have the same length, for example.  Tuples are the closest 
analog to arrays in J.
