Funny you should ask, I was planning to retain the original forms and
my purpose was to avoid adding labels. The less we ask for, the more
likely we are to get it. Besides, I don't really want labels. They would
create a demand for goto...again and that I consider anathema.

There should be a slightly better syntax that would preserve those goals,
but my tired old brain just won't kick one out right now.

Somebody else take a shot.
