/// @assertion A record type declares all of the members defined on [Object]. It
/// also exposes getters for each named field where the name of the getter is
/// the field's name and the getter's type is the field's type. For each
/// positional field, it exposes a getter whose name is $ followed by the number
/// of preceding positional fields and whose type is the type of the field.
///
/// @description Checks that if there is an extension method with the same name
/// as a getter exposed by a record, then the record getter has a higher
/// priority.
