------- Additional Comments from Darin Adler <darin at apple.com>
If speed really matters for Arguments, then we need to do various checks
outside the loops rather than inside, so for example:

    - We need an entirely separate loop for the Arguments case where there are
no deleted arguments.

    - The loop for the parameters should come first, then a separate loop to
handle arguments.
