It looks like rubyish code. There are objects, and callbacks bound by
way of blocks. It's pretty clear how to combine those objects into
larger widgets in an idiomatic, object-functional way. Basically, what
it comes down to is that it is about as abstract as I expect ruby code
to be.

It makes simple things simple. It lets you define the layout
declaratively, which is something I'd love to see in OCaml (and,
indeed, in ruby)
