+Derived classes should declare their attributes using the C<_attributes>
method. They can then inherit the C<init> method from here which will call
accessors of the same name for any values given in the hash passed to C<new>.
Note that you will have to impliment the accessors your self and we expect perl
return wantarray ? %$extra : $extra;
