Yeah, that looks nice.

I wouldn't really consider HAVING a grey area. I think it's only grey
b/c you defined criteria as the "where" clause, but if you change the
definition of Criteria to be "result set selectors" which is
semantically what criteria are anyway, then HAVING fits in nicely.
Although maybe that means that paging should be moved to criteria as
well?

The other option would be to make Criteria strictly "where" clause
stuff, and put HAVING (and LIMIT/OFFSET) into Query.

Also, where does group by go? Does it even need to be handled by
Criteria? Are criteria *solely* for selecting data which will be used
in Propel-managed objects?

I think that I am fine conceptually with Criteria / Query being more
of a "Propel object selector" system than a general way to create
queries, but others may certainly disagree. We just need to pick
either direction so that we can state it in the spec. May require
some further discussion and empirical data from Propel users.

I do still have those... I am using them in my production
environment. I have attached them. Of course they also factor out the
Criteria includes so that may have to change if 2.0 is on PDO...
