=head1 DESCRIPTION |
812
|
|
|
|
|
|
|
|
813
|
|
|
|
|
|
|
This is a small toolkit for generating Moose-like attribute accessors. |
814
|
|
|
|
|
|
|
B<< It does not generate a constructor. >> |
815
|
|
|
|
|
|
|
|
816
|
|
|
|
|
|
|
It stores attribute values inside-out, but it is designed for |
817
|
|
|
|
|
|
|
Sub::Accessor::Small to be subclassed, making it easy to store attributes |
818
|
|
|
|
|
|
|
in other ways. |
