Thanks Bart, that was very deeply informative, it helps me understand 
the bedrock
on which this is all built.  I asked an invalid question. It is not that 
an exit status is or
isn't 'arithmetic', it is that an exit status is not part of a data 
stream.  It is not *what*
it is, but *where* it is that is relevant. I now see that:

     for ((i=1; ! $([ -n "$TLC[i]" ]; echo $?); i++))

... is simple.
