I mean I get it - but, it doesn't feel like ruby to me. It lacks clarity. Maybe it's just me, but i'm not psyched to see this. It feels like a scope creep of some sort.

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.

Lacking clarity is a good word for it, it was my feeling as well, but I've not used Ruby extensively. My feeling trying to hack existing Ruby code was always that Ruby favoured the arcane abit too much. This is from a perspective of me not bothering to learn Ruby at all. I remember thinking the same about C and Python before I bothered learning them.

I guess that feeling is always present when you try languages that are new, or our ignorance of pattern matching/Ruby?
