repeat for each element x in y descending
Now, is that with keys in descending order or elements in descending order?

Sorry, Dar, I used element in the loose sense and really meant chunk
types: char, word, item, line.
When it comes to the 'each element' form, you are right that it is
ambiguous at first glance, but would seem reasonable that sorting
applies to the elements themselves since keys are not explicitly
entering the picture. To get sorting on keys we would need to say
repeat for each line tKey in the keys of myArray ascending
While we can do sorting explicitly with the sort command, I like the
idea of having ascending and descending options as a new feature. It
would combine two steps into a single engine process without a need
to shuffle sorted results back and forth between engine and our
program.
Probably, to make it more complete, we would need to include numeric
and international as options similarly as the sort itself has them.
Now, this has, of course, drifted away from the original request. For
that one, the syntax could be something like
repeat for each foo in foofoo down
No sorting involved, simple reversal of direction. Down is the
closest of the existing keywords for me and already used in another
form of repeat. And the other poster convinced me that even though it
would be slower then forwards, it would still likely has enough speed
benefit.

PS If this needs to be discussed further, may be we should move it to
the improve-list. If anyone is filing it in bugzilla, let us know the
number.
