   Bob Bernecky correctly points out that the real of topic of
discussion should be how to apply an arbitrary function to an
arbitrary subset of an array.

   Unfortunately, I am not willing to be the heavy (read APL2
advocate) in this discussion.  Although I do believe that APL2's
nested arrays are very useful in a wide variety of situations,
in these particular cases (where you're trying to select
subsets of rectangular arrays) I agree that Rank is the correct
solution.  I too wish APL2 included it.

   However, I don't get to call all the shots in APL2 development.
Other people are involved in the decision about what gets into
APL2 in any particular release cycle.

   I don't feel I am qualified to carry on the argument and I feel
there would be a conflict of interest (since I'm on your side
on this one.)

   Hope this doesn't just sound like a cop-out.
