[portland] Interating Tuples Through a List -- RESOLVED

[Rich Shepard]

   A public 'thank you' to Kirby for pointing out what I had forgotten. That
is, to subset a list it is necessary to create a second list with the
appropriate tuples (in my case) from the original list.

   Doing this repeatedly, with the new lists nested, does just what I need to
do.

   Having done this before in other parts of the application I should have
remembered how to do it, but for some reason that completely wiped from
memory.
