That sounds quite useful. I am fairly certain I have wished a feature
like that existed and ended up just wrapping awk with sh but I agree
that's ugly.

Awk is underrated IMHO. Not that json/yaml/etc aren't useful things but
frequently when I seem them used my first thought is "If you had just
done well-formatted text records I could have parsed this with awk".
