fun fact: as far as i can tell, "fv!item" is null-safe for dot properties much like "fv!row" is - meaning, accessing a nonexistent property simply results in a null rather than an error.

a!localVariables(
  local!asdf: {
    {
      idx: 1
    },
    {
      idx: 2
    }
  },
  
  a!forEach(
    local!asdf,
    fv!item.name
  )
)

a!forEach(
    items: local!list,
    expression: if(
        fv!item.b = "R",
        update(
            data: fv!item,
            index: "b",
            value: "T"
        ),
        fv!item
    )
