- have the init_arg be automagically filled in if it is not present

(DONE)

This will simplify some code, and really is not very expensive anyway

- clean up bootstrapping to include the accessors, etc for attributes

(DONE)

Having all this meta-info is useful actually, so why not add it, and 
let the methods get overwritten if they need to be, its a small price
to pay for what we get from it.

- clean up all ->initialize($_[0]) handling

(DONE)
  
We should always be sure that $_[0] is a package name, and not 
a blessed intstance.

- make &compute_all_applicable_attributes not return a HASH

(DONE)

All the info in the HASH is discoverable through the meta-object.

- General Purpose &clone_instance method

(PARTIALLY DONE) - need to implement the deep cloning & tests

It can be a method of the metaclass, like construct_instance is, 
actually it should be called clone_instance, and it should
be thought of as a low-level cloning function, so it should not 
do any blessing or anything of the sort. That is left for the 
class to implement, as is the construct_instance.

- General Purpose &new_object and &clone_object method

(PARTIALLY DONE) - needs more tests

I seem to be writing a new method each time, but since we dont
have a Object class to always inherit from, this is needed.
However, there is nothing to say that I cannot do something like:
 
  Foo->meta->new_object(%params)

and ...

  $foo->meta->clone_object($foo, %params)

Give it some more thought, but I think it is the best way to 
approach this.

- Role/Trait/Scalar-style mixin mechanism

This is fairly simple with the MOP, but the trick comes with 
any SUPER:: calls. This will be a very tricky problem I think.

* see Class::Trait::Base, and maybe use anon-classes for this.
* review the Scalar model for mix-ins
* I like the Class does Role, Role isa Class from Perl 6 idea.

- metaclass.pm

Should handle metaclass incompatibility issue, and do it through 
class mixin composition.

- Prototype-style example

Make a C::MOP::Class subclass which has an AUTOLOAD method, the 
method will DWIM depending up on the value it is passed.

  Foo->prototype->say_hello(sub { print "Hello" });

This will turn into this:

  Foo->prototype->add_method('say_hello' => sub { print "Hello" });

I am not sure how we should handle non-method arguments, mostly 
because those would be static prototype variables, which would 
translate to class package variables. 

- Make a Class::MOP::Package 

Class::MOP::Class would be a subclass of this, but I am not sure 
this is worth the time.
