NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitMismatchedOperators - Don't mix
       numeric operators with string operands, or vice-versa.

AFFILIATION

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

DESCRIPTION

       Using the wrong operator type for a value can obscure coding intent and possibly lead to
       subtle errors.  An example of this is mixing a string equality operator with a numeric
       value, or vice-versa.

           if ($foo == 'bar') {}     #not ok
           if ($foo eq 'bar') {}     #ok
           if ($foo eq 123) {}       #not ok
           if ($foo == 123) {}       #ok

CONFIGURATION

       This Policy is not configurable except for the standard options.

NOTES

       If warnings are enabled, the Perl interpreter usually warns you about using mismatched
       operators at run-time.  This Policy does essentially the same thing, but at author-time.
       That way, you can find out about them sooner.
