Perl::Critic::Policy::Subroutines::ProhibitBuiltinHomonyms - Don't declare your own open function.
open
This Policy is part of the core Perl::Critic distribution.
Common sense dictates that you shouldn't declare subroutines with the same name as one of Perl's built-in functions or keywords. See perlfunc for a list of built-in functions; see perlsyn for keywords.
sub open {} #not ok sub exit {} #not ok sub print {} #not ok sub foreach {} #not ok sub if {} #not ok #You get the idea...
Exceptions are made for BEGIN, END, INIT and CHECK blocks, as well as AUTOLOAD, DESTROY, and import subroutines.
BEGIN
END
INIT
CHECK
AUTOLOAD
DESTROY
import
This Policy is not configurable except for the standard options.
It is reasonable to declare an object method with the same name as a Perl built-in function, since they are easily distinguished from each other. However, at this time, Perl::Critic cannot tell whether a subroutine is static or an object method.
