NAME

Perl::Critic::Policy::Variables::ProhibitNumericNamesWithLeadingZero - Don't use numeric variable names with leading zeros.

AFFILIATION

This Policy is stand-alone, and is not part of the core Perl::Critic.

DESCRIPTION

Numeric variable names with leading zeros are unsupported by Perl, and can lead to obscure bugs. In particular, they are not (or not straightforwardly) accessible as ${0nnn}.

Starting with Perl 5.32, these variables represent a syntax error, so this policy is useless with current Perls. On the other hand, it may be useful for those with an older code base, especially if they are preparing to upgrade it.

CONFIGURATION

This policy supports no configuration items above and beyond the standard ones.

SUPPORT

Support is by the author. Please file bug reports at https://github.com/trwyant/perl-Perl-Critic-Policy-Variables-ProhibitNumericNamesWithLeadingZero/issues or in electronic mail to the author.
