- assignStep:  # these variables can be read by any branch
    assign:
      - input: ["apples", "oranges"]
      - my_result: {}
- parallelStep:
    parallel:
      shared: [my_result]  # my_result is now writable by any branch
      branches:
        - getStock:

                    - temp: 1  # ok, variable is local to branch scope
                    - temp2: "foo"  # ok, variable is local to branch scope
                  # - input: 5  # deployment error, defined in the parent scope but not marked "shared"

                  # - temp: ${temp2}  # deployment error, temp2 is not defined in this branch
