You have an array of arrays, so instead of this:

Code:
foreach(@recs) {
   print "array element: $_\n";
}

you need to dereference the arrays that are in the @recs array:

Code:
foreach (@recs) {
   print "array elements: @{$_}\n";
}

log::dispatch::array

Log::Dispatch::Array(3pm)				User Contributed Perl Documentation				 Log::Dispatch::Array(3pm)

NAME

       Log::Dispatch::Array - log events to an array (reference)

VERSION

       version 1.001

SYNOPSIS

	 use Log::Dispatch;
	 use Log::Dispatch::Array;

	 my $log = Log::Dispatch->new;

	 my $target = [];

	 $log->add(Log::Dispatch::Array->new(
	   name      => 'text_table',
	   min_level => 'debug',
	   array     => $target,
	 ));

	 $log->warn($_) for @events;

	 # now $target refers to an array of events

DESCRIPTION

       This provides a Log::Dispatch log output system that appends logged events to an array reference.  This is probably only useful for testing
       the logging of your code.

METHODS

   "new"
	my $table_log = Log::Dispatch::Array->new(\%arg);

       This method constructs a new Log::Dispatch::Array output object.  Valid arguments are:

	 array - a reference to an array to append to; defaults to an attr on
		 $table_log

   array
       This method returns a reference to the array to which logging is being performed.

   log_message
       This is the method which performs the actual logging, as detailed by Log::Dispatch::Output.
