GROUP BY and aggregate functions are handled by ResultSet in the branch.
DISTINCT should work too.
No idea about HAVING, it's not usually a construct I find myself using.
A "weird SQL SELECTs gallery" (along the lines of the joins gallery I used for
inspiration on 0.03) would be appreciated.
Oh, and I as yet have exactly fsck all idea how to handle sub-SELECTs.
My point more is that via ResultSet you can control the SQL generation pretty
directly by passing appropriate datastructures, and where that doesn't work
literal chunks of SQL. Trying to pass the *whole* SQL at once would simply
ensure that ResultSet couldn't DWIM when you call ->search_related or similar.
