There's the -p flag, but it has other side effects

$ x='() { echo a; }' bash -pc 'echo "$x"'
() { echo a; }

I also dislike that it parses exported functions by default; it violates
the "don't treat data as code" rule. Sure would be nice if there was a
separate flag that only disables parsing of exported functions.
