Note the indention here. pyuic handles it correctly, if you start coding
in column 0.

You should note, that it's currently not possible to handle includes
in a sensible way (do it locally, when needed), nor to create your own 
classes this way. OTOH, this feature is very handy in doing simple 
things. More sophisticated demands gets you back to subclassing in a 
separate module, which isn't that bad, either.
