/// @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 for positional fields a getter is exposed with the
/// name `$` followed by the number of preceding positional fields whose type is
