On CRUD, Scaffolding, ORM and the like.

I'm currently debating whether to rewrite IgnitedRecord from scratch (for PHP 5) or not.

CI's database abstraction isn't really sufficient to make it perform well (I loose about 10-20% performance on CI's abstraction, because of DB_result::result() - even with a very streamlined version).
On the other hand is it hard to do a nice remake which still retains backwards compatibility, yet enables IgnitedRecord to interact with it on a very basic level (almost like IR is calling the database functions).

So if anybody has some wishes for what a good ORM should include (syntax, structure, features, focus, etc.) tell me, because that may convince me to make something awesome!
