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.
