How to create nested computed fields?

Another place where a nested computed field would help @ptpaterson :

Collection Answer

question: Question,
content: {
  select: Boolean | null,
  text: String | null,
  number: Number | null,
  formula: Number | null
}

compute content.formula = (
  doc => (
    if (doc.masterAnswer.formula != null){
        useFormula(doc.masterAnswer.formula, doc)
      }
  )
)

The Use Case is related with the case that we discussed in Privilege elevation in computed fields
