I have code similar to the snippet below:

-- 

class X
def initialize &b
self.class.class_eval &b
end
end

class Y < X
def initialize &b
super(&b)
end
end

a = Y.new do
CONST = 3
end

puts class Y; CONST; end
puts class X; CONST; end

--

Ideally, calling Y's constructor should create a constant in Y and Y alone, 
since self in X#initialize is an instance of Y. However, running this code 
yields 3 and 3 - somehow the constant has been declared in X instead of in 
Y.

What am I doing wrong?

I've tried other variations on self.class.class_eval, including 
self.instance_eval, eval("b.call", binding), all to no avail. Any help would 
be appreciated.
