Class::MOP::Instance - Instance Meta Object
-=head1 SYNOPSIS
-
- # This API is largely internal
- # you shouldn't need it unless you are writing meta attributes or meta
- # instances
-
=head1 DESCRIPTION
The meta instance is used by attributes for low level storage.
Using this API generally violates attribute encapsulation and is not
-reccomended, instead look at L<Class::MOP::Attribute/get_value>,
-L<Class::MOP::Attribute/set_value> for the reccomended way to fiddle with
-attribute values in a generic way, independant of how/whether accessors have
+recommended, instead look at L<Class::MOP::Attribute/get_value>,
+L<Class::MOP::Attribute/set_value> for the recommended way to fiddle with
+attribute values in a generic way, independent of how/whether accessors have
been defined. Accessors can be found using L<Class::MOP::Class/get_attribute>.
This may seem like over-abstraction, but by abstracting

=head2 Operations on Instance Structures
instance it creates. For this reason, any actions on slots
require that the C<$instance_structure> is passed into them.
+The names of these methods pretty much explain exactly
+what they do, if that is not enough then I suggest reading
+the source, it is very straightfoward.
