The ^ operator is maybe a bit confusing, and that Hashes need to use symbol keys to work here is just another example that symbols are a mess. But did you see the JSON-matching example in the slides? That made it totally clear to me how this is supposed to work and what the advantage of having this would be. Very powerful, very useful, and the code in that scenario is much clearer.
