Diesel: A Safe, Extensible ORM and Query Builder for Rust

As a rails developer and someone dabbling with rust on the side, I'm very excited about this! The author is the maintainer of the ruby Active Record gem, which I have a love/hate relationship with.

I recognize "rabidferret" from /r/rust as the author! If he's around to answer questions, I'd be curious about some specific examples/learnings that you took from Active Record as things that you'd definitely 1) want to do or 2) not want to do here.

For example, as someone who's helped out a number of beginner rails developers on IRC and elsewhere, I've found that the distinction between the Active Record object, and the results themselves, is frequently a source of confusion. This could be alleviated by not have #each on the AR object. As another example, I personally am sometimes tripped up by #size using the underlying cached results and #count always triggering a SQL call. Any learnings about the AR API that have affected Diesel's?

Pretty good for a first release, the docs look great already.
