// IsSerialType returns whether or not the input type is a SERIAL type.
// This function should only be used during parsing.
func IsSerialType(typ *T) bool {
	// This is a special case where == is used to compare types, since the SERIAL
	// types are pseudo-types.
	return typ == &Serial2Type || typ == &Serial4Type || typ == &Serial8Type
}

// unreservedTypeTokens contain type alias that we resolve during parsing.
// Instead of adding a new token to the parser, add the type here.
