Hey Sam, great to see you commenting on this :) I started contributing to DM when Dan was already in charge but I was a DM user when you were still working on it. Anyhow, you made really good points here. I've worked on ORMs for a couple of years before I concluded the same - NOT WORTH THE EFFORT. My approach with rom-rb is functional, as in this project works more like persistence libs in functional languages, rather than an O/R mapper. I removed the whole idea of mutable objects and managing their state using UoW etc. This simplified the stack a lot, and despite a complete lack of any performance-related tweaks rom-rb is already faster than ActiveRecord. I also agree with your opinion re validations. I removed this concept from rom-rb as well and built a standalone validation library instead. This works very well. Cheers!
