       Perl::Critic::Policy::ControlStructures::ProhibitUntilBlocks - Write
       "while(! $condition)" instead of "until($condition)".

AAFFFFIILLIIAATTIIOONN
       This Policy is part of the core Perl::Critic distribution.

DDEESSCCRRIIPPTTIIOONN
       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".

CCOONNFFIIGGUURRAATTIIOONN
       This Policy is not configurable except for the standard options.
