This module does not provide any methods. Simply loading it changes the default
naming policy for the loading class so that accessors are separated into get
and set methods. The get methods are prefixed with "get_" as the accessor,
while set methods are prefixed with "set_". This is the naming style
recommended by Damian Conway in Perl Best Practices.

If you define an attribute with a leading underscore, then both the get and set
method will also have an underscore prefix.

If you explicitly set a "reader" or "writer" name when creating an attribute,
then that attribute's naming scheme is left unchanged.
