I had tried the global prefix in the real code (vs. the contrived
example in the post), but in the incorrect code block, which made me
think something else was up. Yes, these were supposed to be constants
that under rare circumstances were changed ;) In the end, I scrapped
the rebind approach, because that wasn't the behavior I wanted
either.Thanks for the help.
