NAME

Perl::Critic::Policy::ControlStructures::ProhibitUntilBlocks

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.
