Mixing model objects and builders leads to static compilation issue

[SimonCockx]

type Person:
    name string (1..1)
    boss Person (0..1)

func ReplaceBoss:
    inputs:
        person Person (1..1)
        boss Person (1..1)
    output:
        result Person (1..1)
    
    set result: person
    set result -> boss:
        if result <> boss  // note: we are using `result` both as a builder object and as a model object
        then boss

leads to

local variables referenced from a lambda expression must be final or effectively final
					if (notEqual(MapperS.of(result), MapperS.of(boss), CardinalityOperator.Any).getOrDefault(false)) {
					                        ^
