Question - Switch syntax support

[ruscoder]

If we need to map one value to another, I think we need an explicit structure, like:

display:
  "{% switch %myCoding.code %}":
    code1: Another Display 1
    code2: Another Display 2
    code3: Another Display 3
    code4: Another Display 4
    "{% default %}": Other

Currently, there are three workarounds to do it.

1. Using fhirpath iif --- too difficult to read (wrong formatting to make it readable!)

iif(%myCoding.code = 'code1', 'Another Display 1',
  iif(%myCoding.code = 'code2', 'Another Display 2',
    iif(%myCoding.code = 'code3', 'Another Display 3',
       iif(%myCoding.code = 'code4', 'Another Display 4', 'Other')
    )
  )  
)

2. Using FPML if/else --- looks not good and similar to option 1. The keys order might lost when formatted.

display:
  "{% if %myCoding.code = ''code1'' %}": Another Display 1
  "{% else %}":
    "{% if %myCoding.code = ''code2'' %}": Another Display 2
    "{% else %}":
      "{% if %myCoding.code = ''code3'' %}": Another Display 3
      "{% else %}":
        "{% if %myCoding.code = ''code4'' %}": Another Display 4

3. Using if and first value --- the most readable option, but looks like a hack

"{% assign %}":
  displayValue:
    - "{% if %myCoding.code = 'code1' %}": "Another Display 1"
    - "{% if %myCoding.code = 'code2' %}": "Another Display 2"
    - "{% if %myCoding.code = 'code3' %}": "Another Display 3"
    - "{% if %myCoding.code = 'code4' %}": "Another Display 4"
    - Other
display: "{{ %displayValue }}"
