RE: trying to be modular

Typically, we worked around this sort of problem in the past by
immediately storing the global fields in a work variable . .

Buck is right on! This is what I also try to do, and I don't
mind creating work variables that I will use later for the
action that I really want to do. Once I decide what "action"
I am going to do, I try to direct the action in it's own
module. Let the actors in the play do what they need to do
to deliver their lines.

Most of the time, I don't worry that I am inefficient
doing several chains to the same record.
Attempt to get away from "getters"
Believe in the "Tell, Don't Ask" pattern.

"You should endeavor to tell objects what you want them to
do; Do not ask them questions about their state.
Make a decision, and then tell them what to do."
