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.
