You should call super if you want to set the member `a`.

~~~ruby
class A
  def initialize(b)
    super(b)
    @b = b
  end
end
~~~

I expected the latest constant to set its @b property. If not Class A, at the very least I expected Struct :a to get set. Is this not the intuitive thing to expect? People send arguments based on param ordering in constant definition. This is totally bypassing that expectation.
