Yeah, I'm not a fan of abstracting away SQL. Lots of other ORMs go that 
direction (and mostly fail in my opinion). Active Record is for 
relational databases and SQL is the best query language for that.

Whatever tighter integration Rails will get with the likes of Madeleine 
and ActiveLDAP will be through duck typing. Not by trying to abstract 
our way out of it.

So the level of abstraction for SQL should only occur to ensure that 
Active Record will work with more databases. And even better, if we can 
NOT do that by implementing something more clever on types and quoting.
