Perl::CrPerl::Critic::UsercContributedpPerlRDocumentationileHandleWithPrint(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.
