-Okay, so here is the basic idea.
-
-First, your metaclass must register with Class::MOP::Immutable
-at which point an anon-class is created which will be the 
-immutable class which your metaclass will be blessed into. 
-
-This allows immutable versions of any metaclass to be created
-on the fly if needed. 
-
-NOTE:
-Remember the immutable version of the metaclass will be used to 
-construct/convert mutable instances into immutable versions. So 
-it itself is a metaclass.
-
-  Class::MOP::Immutable->make_immutable_metaclass(
-      # name of the metaclass we are 
-      # making immutable
-      metaclass => 'Class::MOP::Class',
-      
-      # names of some method metaclasses
-      # which will be useful in the creation
-      # of the immutable versions
-      constructor_class => 'Class::MOP::Method::Constructor',
-      accessor_class    => 'Class::MOP::Method::Accessor',    # ?? maybe
-      
-      # options which the immutable converter
-      # will accept, not exactly sure about 
-      # this one,.. it might have to be hard 
-      # coded in some way.
-      available_options => [qw[
-          inline_accessors
-          inline_constructor
-          constructor_name
-      ]],    
-      
-      # multiple lists of things which can 
-      # be done to the metaclass .. 
-      
-      # make these methods die when called
-      disallow  => [qw[
-          add_method
-          alias_method
-          remove_method
-          add_attribute
-          remove_attribute
-          add_package_symbol
-          remove_package_symbol
-      ]],
-      
-      # memoize the value of these methods
-      memoize   => [qw[
-          class_precedence_list
-          compute_all_applicable_attributes
-          get_meta_instance            
-          get_method_map
-      ]],
-      
-      # make these methods read only
-      readonly  => [qw[
-          superclasses
-      ]],
-  );
-
-Now, this will work just fine for singular metas, but 
-we want this to be able to work for extensions to the 
-metaclasses as well.
-
-Here is how we do that:
-
-  Class::MOP::Immutable->make_immutable_metaclass(
-      # the metaclass name ...
-      metaclass => 'Moose::Meta::Class',
-      
-      # inherit the options from immutable 
-      # parent class (Class::MOP::Class)
-      inherit   => 1
-      
-      constructor_class => 'Moose::Method::Constructor',
-      accessor_class    => 'Moose::Method::Accessor',    # ?? maybe    
-      
-      disallow => [qw[
-          add_roles
-          ...
-      ]],
-      
-      memoize => [qw[
-          roles
-          ...
-      ]]    
-  );
-
-When you specify C<inherit => 1> you are telling 
-Class::MOP::Immutable that you want to inherit your 
-parents options. This means that you get all their
-and yours (perhaps some basic conflict resolution 
-can be added here as well).
-
-It might make sense to also allow a more granular 
-approach such as:
-
-  inherit => {
-      disallow => 'merge',
-      memoize  => 'override',
-      readonly => 'ignore',
-  }
-
-which would allow you to specify in more detail how 
-you would like to handle each change. This might be 
-more than anyone ever needs so we can probably hold 
-off for now.
-
-Ultimately it will be the responsibility of the 
-author to make sure their immutable options make sense.
-
-The reason I say this is that you could easily get 
-carried away in the number of items you choose to 
-memoize or such. This would not make a lot of sense, 
-it would make more sense to memoize at the "topmost"
-level instead, rather than all the intermediate ones.
-
-It's basically gonna be a trade off.
