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.
