=head1 NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitLeadingZeros - Write C<oct(755)> instead of C<0755>.
=head1 AFFILIATION
This Policy is part of the core L<Perl::Critic> distribution.
=head1 DESCRIPTION
Perl interprets numbers with leading zeros as octal.  If that's what
you really want, its better to use C<oct> and make it obvious.
  $var = 041;     #not ok, actually 33
  $var = oct(41); #ok
=head1 CONFIGURATION
This Policy is not configurable except for the standard options.
