Feature #5825: Sweet instance var assignment in the object initializer

I'm very excited about this feature in CoffeeScript, and think it might be a nice-to-have thing in Ruby 2.0.

That's how I think it would look like:

~~~ruby
class Me
  def initialize(@name, @age, @location); end
end
~~~

So we can declare `@variable`s in the initializer method parameters definition to avoid assigning instance variables from method arguments by hand, like:

~~~ruby
class Me
  def initialize(name, age, location)
    @name = name
    @age = age
    @location = location
  end
end
~~~
Want to hear what do you guys think, does that feature worth being included in 2.0?
