I took a simpler route using keywords to tag or name items in a list.
This works now:

--8<---------------cut here---------------start------------->8---
process: foo
  data-inputs
    list
      #:foo 1
      #:bar hello
      #:baz world
  procedure # bash { cat {{data-inputs:foo}} {{data-inputs:bar}} }
--8<---------------cut here---------------end--------------->8---

You can choose to only tag one item if you want; it works just the same:

--8<---------------cut here---------------start------------->8---
process: foo
  data-inputs
    list
      1
      #:bar hello
      world
  procedure # bash { echo {{data-inputs:bar}} }
--8<---------------cut here---------------end--------------->8---
