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.
