Refactoring of attributes/typecasting behavior
Decouples the attribute/typecasting implementation, introducing an Attributes:Store and ActiveRecord::Types. I think this simplifies things and lays the groundwork for other improvements. Assuming this seems like a good idea, I'd like to continue by improving the Types implementation and seeing if it makes sense to extract any other attribute/typecasting behavior.

This is pretty awesome!
But its not applying cleanly for me. Can you please rebase it.
I would love to eventually pull this stuff back into ActiveModel.

This is a great refactoring but it's a huge performance regression: https://gist.github.com/3b5884a2c87755f4015d

Reason :
It's not generating attribute methods properly, making object.column 5x slower. http://github.com/rails/rails/commit/6d30002a52133bd105adb29084f4cc...

Hey guys,
What's the performance goal for this?
Current results: reading attributes is now 3x slower, though a couple methods are a fair bit faster. (query_attribute is 6x faster). The remaining performance differences are due to the longer method call path.
I'd like to explore pulling the @attributes_cache into AR::Attributes and cache most methods by default, performance is then the same or better than 2.3.
Cheers,

Eric, the goal is 2.3 speed or better.
