Description

=begin
The code below raises a LocalJumpError on 1.8.6, 1.8.7, and 1.9 HEAD. It raises a ThreadError ("return can't jump across threads") on 1.8 HEAD.

 def some_method(&b) b end
 a_proc = Proc.new { return }
 res = some_method(&a_proc)
 res.call

Is this difference intentional? If so, why?
