/// @assertion The goal is that you can always tear off a constructor, then
/// invoke the torn off function and get the same result as invoking the
/// constructor directly. For a named constructor it means that
///
///  var v1 = C.name(args);
///  var v2 = (C.name)(args);
//
///  // and
///
///  var v3 = C<typeArgs>.name(args);
///  var v4 = (C<typeArgs>.name)(args);
///  var v5 = (C.name)<typeArgs>(args);
///
/// should always give equivalent values for [v1] and [v2], and for [v3], [v4]
/// and [v5].
///
/// @description Checks that static type of the named constructor is checked
/// correctly for the generic class.
