You're missing `errtrace` (-E) which means "any trap on ERR is inherited by shell functions, command substitutions, and commands executed in a subshell environment"

You probably haven't used it much if you haven't been using `trap`

I use just

   trap EXIT

With

   set -eu

errors in subshells should lead to an exit anyway, so my exit handler is called. Or am I missing some case?

I can't think of any difference if you're trapping both with the same handler. Probably only if you want a separate handler for ERR vs EXIT.

I often set up a temporary directory at the beginning and then clean it up in an EXIT trap. Adding ERR and errtrace (-E) would remove the tmpdir or the first failure anywhere, no matter if it's a recoverable one.

So I'm sticking with just set -eu and trap EXIT...
