Promptable

The instance in scope for A.

The instance of a case class or enum: derives Promptable.

A case class renders as Name(field: value, ...), its fields by their own Promptable (each field's type needs one, or this does not compile); a case without fields, such as an enum's singleton case, as its name. An enum or sealed trait renders each value as its case does; the cases are derived with it.

An instance that renders with f, on its own and nested alike.
