Yeah, I remember the first time I've installed and used Mustache with IcanHaz. It was.. really a pure moment. And then, x.y didn't work and I went crying. Even last week, I had to explain to a new developer why our templates doesn't have the x.y notation and instead have a {{#x}{{y}.. {{/wtf}} notation.

So, I'd be totally willing to help on that part :)
