newRPL: Simplified matrices proposal

[Werner]

Vectors and matrices in RPL are the same object type DOARRY. One of the first parameters in its definition is the number of dimensions - you can create tensors if you like (in ML).
Accessing numeric arrays is much faster than accessing symbolic ones, because the elements are all the same length. For that reason alone, I'd vote against the Grand Unification.
There IS another array type that is not exposed to RPL: the linked array. The type of all elements is still the same, but their lengths may vary (eg decimal integers), and the arry starts with the NxM offsets of all elements, followed by all element 'bodies';

My 2 cents ;-)

Cheers, Werner
