Subject: Bug? Hash::include not working properly

Hi all,

The behaviour of both ruby 1.6 and 1.8 seems broken.
Foo nicely overrides #initialize and #inspect when the module is
included, but Hash does not. Feels like premature optimization to me...

1.8 at least behaves properly when overriding Hash#initialize once more.

Note that the 'discarding old initialize' is on line 22, not line 12.

$ ruby1.6 -v hash_include.rb
ruby 1.6.8 (2003-07-09) [i386-linux]
{}
InsertInit / II: #<Foo:0xb7fd90cc>

$ cat hash_include.rb
module InsertInit
  def initialize(*args)
    super()
    puts "InsertInit / #{self.inspect}"
  end
  def inspect()
    "II: #{super}"
  end
end

class Hash
  include InsertInit
end
p Hash.new()  # {} does not call #initialize at all (only ::allocate?)

class Foo
  include InsertInit
end
p Foo.new("hello")

class Hash
  def initialize(*args)
    super(*args)
  end
end
Hash.new()
