    4.76: How do I define methods for every class/object?

    (contributed by Ben Morrow)

    You can use the "UNIVERSAL" class (see UNIVERSAL). However, please be
    very careful to consider the consequences of doing this: adding methods
    to every object is very likely to have unintended consequences. If
    possible, it would be better to have all your object inherit from some
    common base class, or to use an object system like Moose that supports
    roles.



    --------------------------------------------------------------------

    The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
    are not necessarily experts in every domain where Perl might show up,
    so please include as much information as possible and relevant in any
    corrections. The perlfaq-workers also don't have access to every
    operating system or platform, so please include relevant details for
    corrections to examples that do not work on particular platforms.
    Working code is greatly appreciated.

    If you'd like to help maintain the perlfaq, see the details in
    perlfaq.pod.
