Why doesn't opendir have the same policies as open in Perl Best Practices?

Question

Is there a reason why it opendirdoes not have the same policies openas Perl Best Practices ?

I think of at least these two rules:

• Perl :: Critic :: Policy :: InputOutput :: ProhibitBarewordFileHandles
• Perl :: Critic :: Policy :: InputOutput :: RequireBriefOpen

Answer 1

The original rule from Perl Best Practices (for the first policy you specified) was

Do not use descriptor descriptors

which applies to much more than just that open. Perl :: The critic is mainly based on PBP, but it differs (from perldoc):

Perl:: Critic - Perl. , . Perl:: Critic Perl:: Critic:: Policy, . "Perl Best Practices". Perl:: Critic PBP , Conway.

, , Perl:: Critic opendir, , . , PBP open. CPAN ( , ).

PBP, , opendir. , CPAN , . , .

Answer 2
