Re^2: Print AOA into tab sep values

moritz is right, $" is better than $, ($, leaves a TAB bebore NEWLINE)

Not at all. Just use $, in conjunction with $\.

{
   local $, = "\t";
   local $\ = "\n";
   for my $row ( @out ) {
      print @$row;
   }
}

Of course, the join method much clearer.

Joins are a little more expensive; If the number of elements in @out (num lines * num items per line) is in the millions, using $" is noticeably faster. If the expected size of the output will not be this huge, however, using join is much cleaner, as you pointed out.	[reply]
