NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators - Write " !$foo
       && $bar || $baz " instead of " not $foo && $bar or $baz".

AFFILIATION

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

DESCRIPTION

       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.

           next if not $foo || $bar;  #not ok
           next if !$foo || $bar;     #ok
           next if !( $foo || $bar ); #ok

CONFIGURATION

       This Policy is not configurable except for the standard options.
