Perl::Critic::Policy::Subroutines::ProhibitBuiltinHomonyms(3)
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.
