I read "double quoted" a few times - I think you meant "double-quote'd".

So since it double-quoted, the substitutions occur as you described. And 
whatever results from that becomes a "static" argument/parameter to the 
for-loop.  Is this right?  I recall warnings against using double quotes 
with loops since the substitution occurs once.

I guess I could benefit from this if you explain why the for-loop keeps 
re-evaluating a double-quoted string.
