add .toElement() support

or similar naming, so instead of:

var view = new StreamView(stream);
ul.append(view.el);

you could do:

var view = new StreamView(stream);
ul.append(view);

although this does look like a bug, tough call

+1 this doesn't look like a bug to me, golang does this sort of things, i think it's pretty elegant ;)
