- init:
    assign:
      - workflowScope: foo
- outerLoop:
    for:
      value: outerLoopValue  # outerLoopValue does not exist outside of outerLoop step
      in: [1, 2, 3, 4]
      steps:
        - outerLoopAssign:
            assign:
              - outerLoopScope: ${workflowScope}  # outerLoopScope is a new variable and does not exist outside of outerLoop step
        - innerLoop:
            for:
              value: innerLoopValue  # innerLoopValue does not exist outside of innerLoop step

- final:

      # - ${innerLoopScope}  # not allowed
      # - ${outerLoopValue}  # not allowed
