Is this normal formatting? It looks strange to have the function body
un-indented from the parameter list. (Just trying to learn Dart coding style.)

[Johnni Winther, 2014/09/09 14:21:26]

The body of a passed function expression is indented by 2 spaces from the
call-site. A call split over several line is indented by 4 spaces. These two
conflict visually here making the parameters of the function expression more
indented that the body.

+    dart2js.AstElement dart2jsElement =
+        converter.convertElement(analyzerElement);
+    CpsGeneratingVisitor visitor = new CpsGeneratingVisitor(converter);
+    convertedWorld.executableElements[dart2jsElement] = node.accept(visitor);
+  });
+  return convertedWorld;
+}
