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.
