=head1 NAME

Perl::Critic::Policy::ClassHierarchies::ProhibitAutoloading - AUTOLOAD methods should be avoided.


=head1 AFFILIATION

This Policy is part of the core L<Perl::Critic|Perl::Critic>
distribution.


=head1 DESCRIPTION

Declaring a subroutine with the name C<"AUTOLOAD"> will violate this
Policy.  The C<AUTOLOAD> mechanism is an easy way to generate methods
for your classes, but unless they are carefully written, those classes
are difficult to inherit from.  And over time, the C<AUTOLOAD> method
will become more and more complex as it becomes responsible for
dispatching more and more functions.  You're better off writing
explicit accessor methods.  Editor macros can help make this a little
easier.


=head1 CONFIGURATION

This Policy is not configurable except for the standard options.
