Aha.  So many things to experiment with, and it hadn't occurred to me that the
#persistent directive would be applicable to things other than "variables" -
though I suppose to a certain degree, everything is just an identifier with
"data" stuffed into that bin.
I can see Kenneth salivating now, rubbing his hands together, and getting the
42-cup coffee urn fired up for some very nice animations....   :D

Hmmm.
And I suppose a way to undo that would be #ifdef() and then #undef().
