Thank you! I've been wondering why there aren't more nuanced ORM perspectives in the blogosphere. Yes, OR mapping is a hard problem, and using an OR mapper without some understanding what it does under the hood isn't going to be wonderful. Yes, if performance is paramount, someone out there can write better SQL or NoSQL than the ORM could. But there are an awful lot of use cases where reasonably savvy people use an OR mapper to save themselves a bunch of menial labor, and performance is just fine. It's a tool, not a silver bullet.

"I would love to see some good examples of operator overloading, if you have any to share... "
Check out the Scala combinator parser library. It would be really tedious to use with the traditional method invocation syntax.
Of course, that's Scala, not Java, where you can define your own operators. In Java, there is a fixed set of operators, and overloading is much less interesting. Maybe it really is time to leave Java alone.
