NAME
Perl::Critic::Policy::ControlStructures::ProhibitLabelsWithSpecialBlockNames - Don't use labels that are the same as the special block names.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
When using one of the special Perl blocks "BEGIN", "END", "CHECK", "INIT", and "UNITCHECK", it is easy to mistakenly add a colon to the end of the block name. E.g.: # a BEGIN block that gets executed at compile time. BEGIN { <...code...> } # an ordinary labeled block that gets executed at run time. BEGIN: { <...code...> } The labels "BEGIN:", "END:", etc. are probably errors. This policy prohibits the special Perl block names from being used as labels.
CONFIGURATION
This Policy is not configurable except for the standard options.
