Why isn't this "external String toString();"?

[Lasse Reichstein Nielsen, 2012/08/27 20:48:49]

Agree. Seems like a wasted indirection.

+  void noSuchMethod(String name, List args) {

[Ivan Posva, 2012/08/27 20:11:41]

ditto

+    ObjectImplementation.noSuchMethodImpl(this, name, args);
+  }
+
+  operator ==(other) => this === other;

[Lasse Reichstein Nielsen, 2012/08/27 20:48:49]

return type 'bool'.

+
+  get dynamic() => this;
+}
