One of my D library ideas that fell by the wayside was to make a 
compile-time SQL parser. So you could do something like:

string[] results = Query!("
         SELECT groups.name
             FROM groups
             INNER JOIN employees ON employees.groupId = groups.id,
             GROUP BY employees.groupId
             HAVING avg(employees.salary) > 50000
             WHERE group.name != "Accounting" -- Nobody likes them
             ORDER BY group.name
     ");

(or something like that; my SQL's a bit rusty). Ideally, you could have 
an arbitrarily complex query including subqueries. Query would be a 
template of some sort... not sure exactly how this would work... but 
that's my pipe dream, anyway.
