Not quite. I do understand the above, because it is evident from 
the behavior I am seeing. What I'm puzzled by is why template 
processing behaves this way, requiring that the symbol  be 
defined at the point where it is *passed (by symbol)*, rather 
than where it is *used*, which is the place where having a valid 
definition really matters.
