Updates and inserts on the ORM side of the street are single-object kinds of
things. The pattern is to load a list of objects, make the appropriate
modifications to the those in-memory objects, and then issue a session
flush().

This type of
bulk operation is best done with the SQL generation portion of the library,
like so (using an implicit bound connection here):

   users.update(users.c.group == contractor).execute({users.c.group =
consultant})
