I'd be able to make use of that in my ndarray data type. It would also 
be nice to be able to add things like matrix types, sparse arrays, and 
variable size arrays (ie: list of lists), and subscripting is how you'd 
want to interface with all of those.

Presumably the point type is handled specially today, so that should be 
taken care off too.
