Yeah, it's exec()s you've got to watch out for. You can pretty much
consider $(...) free.

Nonetheless, it's worth going to some effort in long-running or
frequently-run scripts to reduce the number of loops and so forth. sed
and awk can often supplant loops, although I'd not recommend going as
far as Greg Ubben and reimplementing sort(1), dc(1), and much of awk in
sed. (Last I heard he was cracking jokes about implementing perl in
sed, although I think he'd need to add a plugin mechanism first. :) )
