> Also, I'm not sure I agree with claim of readable output js: http://somebee.github.io/todomvc-render-benchmark/todomvc/im.... (look at tag.prototype.render). It's not exactly clean, although it's not terrible either.

You are absolutely right, and I agree. When you use static tag trees in Imba (with inline caching) the code is not readable. If you only use it for regular things you would write in js (classes, functions, etc) I still think it is quite readable.

BTW, I really love the simplicity of Mithril. It is a very impressive project.
