TransformingPropertyMap

public struct TransformingPropertyMap<NewValue, Underlying> : PropertyMap where Underlying : PropertyMap
extension TransformingPropertyMap: ParallelCapablePropertyMap where Underlying: ParallelCapablePropertyMap

Transforms an existing property map (Underlying) to project out a single underlying field from its Value.

Beware: this results in extra copies when mutating the underlying values.
