What does NaCL have to do with Google APIs? It's a client side technology. You can talk to whatever server(s) you want. (Presumably subject to same origin policy like JS, which if anything means it's easier to talk to your servers rather than Google's or someone else's).

I don't know exactly what NaCL does, but the JVM/CLR verification is all about making sure you don't write over someone else's memory, jump to some arbitrary address, etc. Essentially the problem is: how do you run untrusted code in the same address space, without it getting all of your process's permissions.

It's a very early tech preview.

And pretty much all functional languages get by just fine without semicolons (Lisp, ML, Haskell, etc).

http://www.dartlang.org/docs/technical-overview/index.html has some information on the design goals.

See http://blog.chromium.org/

There's a compiler that translates to JavaScript, and a standalone VM.

Yeah, there are more links to code samples here: http://www.dartlang.org/samples/index.html

Here's what I don't get about QR codes: why not just use URLs and OCR them? OCR seems to be pretty good these days, and you could always print the URL with a font of your choice (e.g. pick something easy to OCR).

And you get this cool feature ... humans can read them, too.

That's funny, I've usually had the opposite experience with Qwest (in Seattle): inconsistent results in speed tests, but very consistently good download times for large files. Tis strange.

Python's colon-before-indented-block resulted from usability tests of people learning how to program. I don't see why that would have different results today.

You're right about the port. Here's a link to the Harbor Island map (in Seattle, WA where we get lots of shipments from Asia), note proximity of rail lines:

I don't know much about it, but the machinery at the port looks really impressive. It seems to lift cargo from the ships onto the trains.

Agreed, it would be nice to see the bug. AFAIK they take standards compliance pretty seriously. I'm sure someone would look at it, especially if Chrome is behaving differently from FF/IE9/Safari.

JavaScript automatic semicolon insertion is definitely considered to be a mistake (judging by es-discuss), but many many other languages allow newlines as statement separators without problems. It seems to be fine as long newlines are only allowed under certain circumstances within expressions, such as only in grouping constructs () [].

That's a fair point. Would the AST strawman proposal (http://wiki.ecmascript.org/doku.php?id=strawman:ast) get you most of the way there? If nothing else, it would make some metaprogramming of the source tree possible. Combine that with module loaders (http://wiki.ecmascript.org/doku.php?id=harmony:module_loader...) and I think you're pretty close to macros.

One of the devs here. It's definitely not intended to be a new language. My understanding is "text/traceur" was chosen because some of the features haven't been accepted officially into harmony yet (i.e. they are strawman proposals: http://wiki.ecmascript.org/doku.php?id=strawman:strawman), in particular classes/traits and async.
