Thanks for your feedback!

Check out this other proof of concept demonstrating ES6 style object destructuring in Ruby:

https://github.com/lendingHome/destruct

I think this same type of concept could be applied to port Elixir style pattern matching as well e.g.

    data = {
      name: "John Smith",
      age: 35,
      prefs: {
        lang: "en",
        tz: "UTC",
      }
    }
    
    User = Pattern { name age prefs[lang] }
    
    user = User =~ data
    user.name
    user.age
    user.lang
    
    [data].map(&User)
    
    case object
    when Pattern { some attrs[:nested][real][deep, fields] }
      Pattern!.some
      Pattern!.real
      Pattern!.deep
      Pattern!.fields
      Pattern!.nested #=> NoMethodError
    end
    
    # or define "locals" by defining temporary methods on
    # the block receiver when the "then" block is evaluated
    case object
    when Pattern { some nested[data] }.then do
      puts some
      puts data
    end
