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.
