[rules-dev] Long DSL lines

[Michael Neale]

only objection I would have is that the error numbers in the expanded syntax
(should there be compile errors) would not line up with the source (which
makes it slightly more annoying than it already is to sort out).

But as this thread goes on, perhaps some more holistic thought to what we
want DSLv2 to be like is in order.
