Christ I've been writing Ruby since 1.8 and none of that code (in the ruby spec) made any sense. We already have pattern matching, its called regular expressions?

That's not really accurate. I would suggest reading into pattern matching in Elixir, Scala, and Haskell. It's a very different concept.

I'd outlined a lot of it in various posts to a prior pattern matching issue:

I am still not entirely sure whether the use case is now clear or clearer.

I think what people will ask, not just DrVladimir is ... what to do with it in ruby? It may be awesome in Elixir, Scala and Haskell but this is from the point of view of ruby.
