Perl::Critic::Policy::ValuesAndExpressions::ProhibitLeadingZeros − Write "oct(755)" instead of "0755".
This Policy is part of the core Perl::Critic distribution.
Perl interprets numbers with leading zeros as octal. If that’s what you really want, its better to use "oct" and make it obvious.
$var = 041; # not ok, actually 33 $var = oct(41); # ok chmod 0644, $file; # ok by default dbmopen %database, 'foo.db', 0600; # ok by default mkdir $directory, 0755; # ok by default sysopen $filehandle, $filename, O_RDWR, 0666; # ok by default umask 0002; # ok by default
If you want to ban all leading zeros, set "strict" to a true value in a .perlcriticrc file.
[ValuesAndExpressions::ProhibitLeadingZeros] strict = 1
