Hi everyone,

I've noticed that errexit is disabled inside command substitution.
Is this intentional?

It makes it hard to save and restore errexit state. I.e. you can't simply say
opts=`set +o`, because errexit will always be stored as off. What's
interesting, $SHELLOPTS shows it still on inside the command substitution.
