Perl::Critic::Policy::ControlStructures::ProhibitUntilBlocks - Write while(! $condition) instead of until($condition).
This Policy is part of the core Perl::Critic distribution.
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.
This Policy is not configurable except for the standard options.
