-  // Technically we could just use noSuchMethod to implement [call], but we

-  //   * noSuchMethod makes the code a lot bigger.
-  //   * even with noSuchMethod, an analyzer bug requires to declare [call] (see
-  //     dartbug.com/16078).
-  //   * having [call] also allows `is` checks to work for functions of 0
-  //     through 3 arguments.  We depend on this in
-  //     `polymer_expressions/lib/eval.dart` to check whether a function is a
-  //     filter (takes a single argument). (Note that it's possible to include
-  //     both [call] and [noSuchMethod], which would make instance-of checks
-  //     work with the signature of [call], but will allow invoking the function
-  //     using [noSuchMethod].
