/// @assertion We allow tearing off named constructors.
//
// If [C] denotes a class declaration and [C.name] is the name of a constructor
// of that class, we allow you to tear off that constructors as:
//
//  C.name, or
//  C<typeArgs>.name
//
// just as you can currently invoke the constructor as [C.name(args)], or
// [C<typeArgs>.name(args)].
///
/// @description Checks that tearing off named constructor without type
/// arguments is allowed for a generic class.
