Perl::Critic::Policy::ControlStructures::ProhibitLabelsWUserpContriPerl::Critic::Policy::ControlStructures::ProhibitLabelsWithSpecialBlockNames(3)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.

Perl::Critic::Policy::ControlStructures::ProhibitUntilBlocks - Write "while(! $condition)" instead of "until($condition)".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway discourages using "until" because it leads to double-negatives that are hard to understand. Instead, reverse the logic and use
"while".
until($condition) { do_something() } #not ok
until(! $no_flag) { do_something() } #really bad
while( ! $condition) { do_something() } #ok
This Policy only covers the block-form of "until". For the postfix variety, see "ProhibitPostfixControls".
CONFIGURATION
This Policy is not configurable except for the standard options.

Newbie question, not sure of the use of BEGIN when you can just have the enclosed code inserted before the remaining program which means that code will get executed first anyway? (2 Replies)
