perl::critic::policy::valuesandexpressions::prohibitmismatchedop
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.
