NAME

Perl::Critic::Policy::Subroutines::ProhibitBuiltinHomonyms - Don't declare your own open function.

AFFILIATION

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

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.

CONFIGURATION

This Policy is not configurable except for the standard options.

CAVEATS

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.
