CentOS 7.0 - man page for perl::critic::policy::inputoutput::requirebracedfilehandlewithprint (centos section 3)

Perl::Critic::Policy::InputPerl::Critic::Policy::InputOutput::RequireBracedFileHandleWithPrint(3)

NAME
       Perl::Critic::Policy::InputOutput::RequireBracedFileHandleWithPrint - Write "print {$FH}
       $foo, $bar;" instead of "print $FH $foo, $bar;".

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

DESCRIPTION
       The "print" and "printf" functions have a unique syntax that supports an optional file
       handle argument.  Conway suggests wrapping this argument in braces to make it visually
       stand out from the other arguments.  When you put braces around any of the special
       package-level file handles like "STDOUT", "STDERR", and "DATA", you must the '*' sigil or
       else it won't compile under "use strict 'subs'".

	 print $FH   "Mary had a little lamb\n";  #not ok
	 print {$FH} "Mary had a little lamb\n";  #ok

	 print	 STDERR   $foo, $bar, $baz;  #not ok
	 print	{STDERR}  $foo, $bar, $baz;  #won't compile under 'strict'
	 print {*STDERR}  $foo, $bar, $baz;  #perfect!

CONFIGURATION
       This Policy is not configurable except for the standard options.
