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.

~~~ruby
A = Struct.new(:a)

A.new(1)
#<struct A a=1>

class A
  def initialize(b)
    @b = b
  end
end

A.new(1)
#<struct A a=nil>
~~~

Is this expected?
