Perl::Critic::Policy::ControlStructures::ProhibitLabelsWUserpContPerl::Critic::Policy::ControlStructures::ProhibitLabelsWithSpecialBlockNames(3pm)NAMEPerl::Critic::Policy::ControlStructures::ProhibitLabelsWithSpecialBlockNames - Don't use labels that are the same as the special block names.AFFILIATIONThis Policy is part of the core Perl::Critic distribution.DESCRIPTIONWhen 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.CONFIGURATIONThis Policy is not configurable except for the standard options.SEE ALSOThe Perl Buzz article on this issue at http://perlbuzz.com/2008/05/colons-invalidate-your-begin-and-end-blocks.html <http://perlbuzz.com/2008/05/colons-invalidate-your-begin-and-end-blocks.html>.ACKNOWLEDGMENTRandy Lauen for identifying the problem.AUTHORMike O'ReganCOPYRIGHTCopyright (c) 2008-2011 Mike O'Regan.
