Changing existing code to use a 'CHOICE'-like util would require some tweaking.
This would be worthwhile, assuming it was done well, if it made the code
smaller, easier to read, and easier to run.
Or suppose for the sake of argument that no existing scripts were tweaked to
use such a util... too much work, nobody wants to do it, or has the time, and
there's always the danger of introducing new bugs.
Even so, a 'CHOICE'-like util would make new scripts easier to write -- all
other things being equal, wouldn't you rather write one line of code instead of
three or four?
