Writeable CTE is definitely the bigger feature. Effectively, it allows
people to do in a single query data-transformation operations which
would have taken a stored procedure before. Think of it as comparable
to the introduction of callbacks in Perl for coolness.

Hmmm, that's potentially lethal. David Fetter has been doing a lot of
presentations on the feature; surely he could turn them into some
documentation? David?
