Note that I framed it as "not exactly honest" rather than saying it's an overt lie. Because I don't consider it an overt lie, but it's hard not to read it as a bit equivocal to claim that asm.js as just JavaScript.

And really, I'm far more concerned with the future plans, particularly with regard to things like multi-threading APIs. I don't see how those can be incorporated in a way that supports asm.js as an easy target for existing code while not causing it to diverge from JavaScript as used in the browser.
