Dear Bash-developers,
Recently I came across a surprising undocumented bash-feature
$ for i in 1 2 3; { echo $i; };
The usage of curly-braces instead of the well-documented do ... done
construct was a complete surprise to me and even lead me to open the
following question on stack overflow:
Are you trying to run autocompletion on an nfs mount? Are you using ''ls''
to autocomplete and if so did you run \ls /path/to/dir .. ?
Maybe worth to mention the bash version you are using.

I wonder why wait $! doesn't do the job here.

So instead of your contrived case, write it properly. Check the process

So if I understand correctly, you reported the lack of wait $! || exit

Hi,
It may be a surprise to some that this code here winds up printing
"done", always:
$ cat a.bash
set -e -o pipefail
while read -r line; do
echo "$line"
done < <(echo 1; sleep 1; echo 2; sleep 1; false; exit 1)
sleep 1
echo done
$ bash a.bash
1
2
done
