I love this. +1000.
As I've said previously, I think pattern matching would pair exceptionally
well with EcmaScript, and refutable destructuring is a great first step
towards that. After a little bit of use, I expect the community to demand
it, even if they aren't familiar with it in other languages.
"I want to destructure here, but I have a couple of possible options. If
only there was some kind of switch case with pattern matching..."
No chance of getting pattern matching in for ES6 by any chance, is there? ;)
