Agreed... though it's a nice reminder that GopherJS is still an option... I was actually hoping that it was some sort of NaCl option for Go.
That said, I'd also love to see the ability to write native node.js modules via go. Channels would be a pretty natural interface for native modules from node via go. And could probably do something via named-pipes, but a transparent integration would be so cool.
I was hoping someone finally figured out a good way to start the Go runtime from node/c/c++. Once this feature exists it will be trivial to write Go extensions/modules for Chrome, Apache, Node, MySQL, you name it.
Go -> Gopherjs -> Javascript running like any other Chrome extension. Go isn't running in Chrome extensions as "native client" here.
