Great comments. I have thought about creating an interface so people can just implement their own query evaluation methods and, as you said, do querying from remote data sources. That's still a long-term plan, though, I probably need to see somebody using it before digging that deep.

Does golang support reified code/expression trees/quoted code/whatever you wanna call it? That seems to be a rather critical part of making it work.

Or you use RethinkDB's RQL approach, which implements a bunch of functions that record what you did, at the cost of not being able to put relatively arbitrary expressions inside the query.

Or how else do you translate ".Where(x -> x.Age > 10)" into SQL?
