Using sh to generate a map?

I've been taking a poke at https://github.com/go-task/task/issues/1585 very briefly but it made me wonder if there would be interest in something that would support using the output of a sh: into a map. This would allow me to create complex tasks or scripts that generate valid JSON for consumption by task (something I already do regularly for GitHub Actions matrixes). For instance:

---
version: 3

tasks:
  foo:
    vars:
      BAZ:
        sh: 'echo "{a: 1, b: 2, c: 3}"'
      FOO:
        map: '{{.BAZ}}'
    cmds:
      - 'echo {{.FOO.a}}'

---
version: 3

tasks:
  foo:
    vars:
      BAZ:
        sh: 'echo "{a: 1, b: 2, c: 3}"'
      FOO:
        map: '{{.BAZ}}'
    cmds:
      - 'echo {{.FOO.a}}'

Or, a more streamlined:

---
version: 3

tasks:
  foo:
    vars:
      FOO:
        map:
          sh: 'echo "{a: 1, b: 2, c: 3}"'
    cmds:
      - 'echo {{.FOO.a}}'

---
version: 3

tasks:
  foo:
    vars:
      FOO:
        map:
          sh: 'echo "{a: 1, b: 2, c: 3}"'
    cmds:
      - 'echo {{.FOO.a}}'

Hi @JonZeolla, I suggest you do make a comment on https://github.com/go-task/task/issues/1585 with your proposal. There, it would be less likely to be forgotten, as Discord is more for questions than feature requests.
