 * @assertion Dart supports two levels of privacy: public and private.
 * A declaration is private iff its name begins with an underscore (the _ character) 
 * otherwise it is public.
 * A declaration m is accessible to library L if m is declared in L or if m is public.
 * @description Checks that type parameter names can begin with an underscore and
 * are still accessible in the appropriate scope.
