------------------------------------+---------------------------------------
 When you call super in macruby, it doesn't pass any blocks along; which is
 counter to the behavior in other rubys and causes gems that use this
 functionality, such as Mechanize (see #1218, #1182) to fail.

 See the following code:

 {{{
 class Foo
   attr_accessor :a, :b
   def initialize(a)
     @a = a
     yield self if block_given?
   end
 end

 class Bar < Foo
   attr_accessor :c
   def initialize(a, c)
     @c = c
     super(c)
   end
 end

 # MacRuby 0.10
 Bar.new(1, 3) {|foo| foo.b = 2} #=> <Bar:0x2003e80a0 @c=3 @a=3>

 # Ruby 1.9.2
 Bar.new(1, 3) {|foo| foo.b = 2} #=> <Bar:0x000001009b85b0 @c=3, @a=3,
 @b=2>
 }}}

 For those interested, I made a patch to Mechanize 2.0.pre.2
