    vars:
      school: Sydney Grammar
    dvars:
    - name: nv #case 1: reference to dvar
      value: "n=>{{.school}}"
    - name: m
      value: m=>{{.nv}}
      expand: 1
      desc: |
        the expand should be 1 as n is already instanciated a actual value
    - name: j
      value: j=>{{.m}}
      expand: 1
      desc: |
        the expand should be 1 as n is already instanciated a actual value
      #case 2: reference to var
    - name: o
      value: o=>{{.c}}
      expand: 3
      desc: |
        the expand should be 3 as the reference in vars not evaluated yet
        this eventually will be the value of school from vars
      #case 3: it allows you to put non templated string there as value in dvars
    - name: z
      value: i am zzz
      desc: you can use plain string here too
    - name: yv
      value: y->{{.z}}
    - name: x
      value: x=>{{.yv}}
      expand: 1
      desc: |
        you can't expect to use expand level 2 to get value z, as there is no need
        to do so because y should be already rendered
