Yea, we were talking about that a couple days go. Awesome. I'm getting deep into Polymer, so WebComponents were already on my
mind. From that thread:
Kind of cool. Kind of obvious. They say they're not going to add / change much or anything, but then they hint about fixing some
other things. Could be good. Mostly, this is just to avoid parsing and not much else different.
Because of the binary XML work, I probably have a lot of insight into the problems here... If I weren't so busy. Wonder what it
would take to get an invite to the group.
The comments about supporting languages other than C/C++ are weird. What are they doing that is language specific? I think
glue to update.
The more cool thing that's happening is that Swagger is going everywhere. Apigee has been big, already public. (A while back, I
think I met someone who works there.) I saw a reference to Google doing something with it, but couldn't find that yet. There's a
mapping from Google Discovery to Swagger. Microsoft is including Swagger in the next version of Visual Studio. Etc.
I should have pointed out several big things that were mentioned here or near:
1) Webassemblies will allow asm.js based modules, i.e. C++ etc., to be used easily in web pages as WebComponents, which is a new
2) Adding threads, full SIMD, zero-cost exception handling for C++
3) We've moved to a post-versioned world, at least with respect to the browser itself. The idea is that you specify that your
framework, libraries, and other dependencies work on "Evergreen" browsers and other technologies. This is partially made to work by
A) everyone upgrading automatically to the newest version of each browser and B) polyfills to fill in gaps when a particular browser
hasn't caught up with the current consensus target features. We now have enough building blocks in most cases that new features can
be implemented somewhat in old features until they actually are native. In some cases, those features might never actually be

Now if we could just get WebGL 2, 3..., WebCL, WebUSB, SIMD.js, etc. in place, we'd be getting somewhere.

As reflected in the high-level goals <https://github.com/WebAssembly/design/blob/master/HighLevelGoals.md>, a central requirement for WebAssembly is that it integrate well with the rest of the Web platform and that the initial version <https://github.com/WebAssembly/design/blob/master/MVP.md> run efficiently on current browsers using a client-side polyfill <https://remysharp.com/2010/10/08/what-is-a-polyfill/>. As demonstrated <https://github.com/WebAssembly/design/blob/master/FAQ.md#can-the-polyfill-really-be-efficient>, the polyfill can leverage asm.js to get great performance. For existing Emscripten/asm.js users, targeting WebAssembly will be as easy as flipping a flag <https://github.com/WebAssembly/design/blob/master/FAQ.md#whats-the-story-for-emscripten-users>. Thus, it is natural to view WebAssembly as the next evolutionary step of asm.js (a step many have requested and anticipated).

Going forward, there will be a lot more iteration and experimentation under the WebAssembly <http://github.com/webassembly> GitHub organization. For questions, check out the still-emerging FAQ <https://github.com/WebAssembly/design/blob/master/FAQ.md>. Brendan Eich also has a vibrant blog post <https://brendaneich.com/2015/06/from-asm-js-to-webassembly> with more context, history and JS perspective.
