NAME

       Perl::Critic::Policy::CodeLayout::ProhibitParensWithBuiltins - Write "open $handle, $path"
       instead of "open($handle, $path)".

AFFILIATION

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

DESCRIPTION

       Conway suggests that all built-in functions be called without parentheses around the
       argument list.  This reduces visual clutter and disambiguates built-in functions from user
       functions.  Exceptions are made for "my", "local", and "our" which require parentheses
       when called with multiple arguments.

           open($handle, '>', $filename); #not ok
           open $handle, '>', $filename;  #ok

           split(/$pattern/, @list); #not ok
           split /$pattern/, @list;  #ok

CONFIGURATION

       This Policy is not configurable except for the standard options.

NOTES

       Coding with parentheses can sometimes lead to verbose and awkward constructs, so I think
       the intent of Conway's guideline is to remove only the unnecessary parentheses.  This
       policy makes exceptions for some common situations where parentheses are usually required.
       However, you may find other situations where the parentheses are necessary to enforce
       precedence, but they cause still violations.  In those cases, consider using the '## no
       critic' comments to silence Perl::Critic.

BUGS

       Some builtin functions (particularly those that take a variable number of scalar
       arguments) should probably get parentheses.  This policy should be enhanced to allow the
       user to specify a list of builtins that are exempt from the policy.
