Perl::Critic::Policy::ValuesAndExpressions::ProhibitMismUsereContributPerl::Critic::Policy::ValuesAndExpressions::ProhibitMismatchedOperators(3pm)

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.
