Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators - Write !$foo && $bar || $baz instead of not $foo && $bar or $baz.
!$foo && $bar || $baz
not $foo && $bar or $baz
This Policy is part of the core Perl::Critic distribution.
Conway advises against combining the low-precedence booleans ( and or not ) with the high-precedence boolean operators ( && || ! ) in the same expression. Unless you fully understand the differences between the high and low-precedence operators, it is easy to misinterpret expressions that use both. And even if you do understand them, it is not always clear if the author actually intended it.
and or not
&& || !
next if not $foo || $bar; #not ok
next if !$foo || $bar; #ok
next if !( $foo || $bar ); #ok
This Policy is not configurable except for the standard options.
