-NOTES
-
-Okay, the metaclass constraint issue is a bit of a PITA.
-
-Especially in the context of MI, where we end up with an
-explosion of metaclasses.
-
-SOOOO
-
-Instead of auto-composing metaclasses using inheritance
-(which is problematic at best, and totally wrong at worst,
-especially in the light of methods of Class::MOP::Class
-which are overridden by subclasses (try to figure out how
-LazyClass and InsideOutClass could be composed, it is not
-even possible)) we use a trait model.
-
-It will be similar to Class::Trait, except that there is
-no such thing as a trait, a class isa trait and a trait
-isa class, more like Scala really.
-
-This way we get several benefits:
-
-1) Classes can be composed like traits, and it Just Works.
-
-2) Metaclasses can be composed this way too :)
-
-3) When solving the metaclass constraint, we create an
- anon-metaclass, and compose the parent's metaclasses
- into it. This allows for conflict checking trait-style
- which should inform us of any issues right away.
-
-Misc. Details:
-
-Class metaclasses must be composed, but so must any
-associated Attribute and Method metaclasses. However, this
-is not always relevant since I should be able to create a
-class which has lazy attributes, and then create a subclass
-of that class whose attributes are not lazy.

-metaclass - a pragma for installing using Class::MOP metaclasses
+metaclass - a pragma for installing and using Class::MOP metaclasses
=head1 SYNOPSIS
+ package MyClass;
+
+ # use Class::MOP::Class
+ use metaclass;
+
+ # ... or use a custom metaclass
use metaclass 'MyMetaClass';
+ # ... or use a custom metaclass
+ # and custom attribute and method
+ # metaclasses
use metaclass 'MyMetaClass' => (
':attribute_metaclass' => 'MyAttributeMetaClass',
':method_metaclass' => 'MyMethodMetaClass',
=head1 DESCRIPTION
This is a pragma to make it easier to use a specific metaclass
-and it's
+and a set of custom attribute and method metaclasses. It also
+installs a C<meta> method to your class as well.
