You can still use GET and PUT to access individual elements of arrays, and as Gilles mentions, converting them to a list (and back) is easy with AXL. So processing a single-dimension array isn't drastically different than a list, it just requires a bit of transformation at key points.

More care is needed when dealing with matrices, as the distinction between a multi-dimensional array and a matrix is something the user (or programmer in this case) has to keep in mind. It may make perfect sense in the context of a multi-dimensional array to expect

Code:

[
  [ 1 2 ]
  [ 3 4 ]
]
[
  [ 1 1 ]
  [ 1 1 ]
]
*

to result in

Code:

[
  [ 1 2 ]
  [ 3 4 ]
]

But of course, that's not what's going to happen if you actually execute that on a 50g. So transforming those matrices to list form could facilitate a different contextual meaning.

Which commands (either old or new) do you see as candidates for such treatment?
