The problem is with multi-dimensional indices.
Consider:
a[$-1][$-2];
There are two different values for $.
Right. I don't understand why a solution like length does not apply, and
why opDollar would. In the above example, both a and a[$-1] should have
a length member or an opDollar method. What do I misinterpret?
I believe Don made a typo:
a[$-1, $-2];
