I do :)

I'm solidly behind the proposals to use a DSEL for describing GUI
elements. It's the right level of abstraction for the task. I'm not sure
I'm a big fan of the '+' syntax you propose, if only because it requires a
lot of discipline to make it look "right", whereas an approach that uses,
e.g., [] or () to perform grouping will at least make my editor do the
right thing.
