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