/// @assertion A super parameter generates an implicit argument that forwards to

/// public, even if the corresponding constructor parameter uses this feature
/// and has a private name. Thus, super parameters continue to always use public
/// names.

/// @description Check that private super parameter can be invoked using its
/// public name.
