The idea i was hoping to pull off here is that every statement was,
implicitly, a try block and any exception raised by it could have
handlers associated, and a block that would only follow if it did not
raise an exception.

However, I never thought it was a great idea, but this is python-ideas
not python-good-ideas ;-)

Steven has already convinced me it was a bad idea from a maintenance standpoint.
