Feature #6414: Destructuring Assignment

I mean:

john = {name: "John", last: "Smith"}
{name, last} = john # extract value by key from the hash and set to local variable with same name
name # => "John"
last # -> "Smith"

Useful for ex. for  "options" hashes:
def select(options={})
  {only, except} = options
  ...
end

As extra part of this feature can be hash constructing in this way:

name = "John"
last    = "Smith"
find({name, last}) # equals to => find({name: "John", last: "Smith"})

I think both really nice to have in Ruby.
Thanks.
