/// @assertion In general, a non-generic type alias is just expanded to its

/// [IntList.filled] will act like tearing off [List<int>.filled], it
/// automatically instantiates the class type parameter to the specified type.

/// type parameter to the specified type for non-generic type alias. Test
/// negative dynamic case for [List<int>].
