(John, there’s another type of field called an
AsyncField
, which indicates that we need the engine for hydration. You call
await Get[SourcesResult](Sources, my_tgt.get(Sources)
, rather than
my_tgt.get(Sources).value
. Only about 5-10% of fields are `AsyncField`s. They’re orthogonal to this discussion because `AsyncField`s are by definition always lazy.)
