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