Current asm.js is just for C/C++. Those altJS languages can't make use of asm.js (Haxe->C++->LLVM->Emscripten->asm.js might be possible but I think it's meaningless).

asm.js is the answer of Mozilla for "the web standards can't handle AAA games" but I believe this is far from an ideal solution. And I agree with the worry of the poster that this ugly hack makes JavaScript more ugly, both on the specs and VMs.

To be honest, I trembled when I saw the Math.imul proposion to see how some people are so obsessed with JavaScript...

There is already asm.js support for lljs, some thoughts on support in things like JSIL (C#) and Haxe (as you mentioned).

And in principle anything that compiles to LLVM IR or C/C++ would work through emscripten.

I think that's a dangerous way of putting it. Asm.js is just a spec and can (and ought to) be emitted by things other than Emscripten.

As others have mentioned, I don't see asm.js as being fundamentally tied to C/C++. Please correct me if I'm wrong. Memory management could be addressed in future versions, but even if it is not, there are still ways of getting the performance benefit of asm.js using altjs.
