-=head1 NAME
-
-Perl::Critic::Policy::ControlStructures::ProhibitUntilBlocks - Write C<while(! $condition)> instead of C<until($condition)>.
-
-=head1 AFFILIATION
-
-This Policy is part of the core L<Perl::Critic> distribution.
-
-
-=head1 DESCRIPTION
-
-Conway discourages using C<until> because it leads to double-negatives
-that are hard to understand. Instead, reverse the logic and use C<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 C<until>. For the postfix
-variety, see C<ProhibitPostfixControls>.
-
-
-=head1 CONFIGURATION
-
-This Policy is not configurable except for the standard options.
