=head1 NAME

Perl::Critic::Policy::Miscellanea::ProhibitTies - Do not use C<tie>.


=head1 AFFILIATION

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


=head1 DESCRIPTION

Conway discourages using C<tie> to bind Perl primitive variables to
user-defined objects.  Unless the tie is done close to where the
object is used, other developers probably won't know that the variable
has special behavior.  If you want to encapsulate complex behavior,
just use a proper object or subroutine.


=head1 CONFIGURATION

This Policy is not configurable except for the standard options.
