Please add a blank line after the namespace declaration.

Done.

We should teach the code generator how to generate this code.  We'll want to add
an IDL attribute for [ImplementedInJavaScript] or something of that nature.

[yhirano, 2013/06/18 08:56:15]

Will do in another CL.

 
+void V8Promise::getMethodCustom(const v8::FunctionCallbackInfo<v8::Value>& args)
+{
+    v8SetReturnValue(args, V8PromiseUtilities::callUnwrappedMethod("get", args, V8PromiseUtilities::promisePrototype(args.GetIsolate())));
+}
 
 } // namespace WebCore
