Notes from the July 8 Dart language design meeting

The incomporable  Bob Nystrom  fills us in on the language design discussions taking place amongst Dart engineers. Here are his  notes from the July 8th language meeting : Here's my notes! JS interop and proxies Lars tried to make a little app using JS interop. He gets warnings from dart2js because JS interop returns a proxy. The only way to get rid of the warnings is to edit the interop package itself to make it return the dynamic type.

Introducing polymer.dart

Dart engineer John Messerly announces the launch of polymer.dart, a port of the  Polymer stack . The Web UI package will be maintained for some time, but will eventually be replaced by polymer.dart. Here is John's  original post introducing polymer.dart : Hello Dartisans, Since we started Web UI, we've had a goal to bring the latest web standards like Web Components and Model-Driven Views to Dart developers.

Last but not least: the development of the Poly
