`set -eu` translated as empty `(do)`

[dundalek]

I have some scripts starting with set -eu. Given babashka has a sane default by throwing on error, it makes sense the setting can be ignored.

This is a minor detail, output ends up with extraneous (do) which could be omitted.

set -eu
echo a

#!/usr/bin/env bb

(require (quote [babashka.process :refer [shell pipeline pb]]))
(do)
(shell "echo" "a")

Fixed! I had a baked in assumption in the code that every ast element translated into exactly one form. Removing this (incorrect) assumption required a bit of refactoring.
