Update: Answered the wrong question.

This is tougher than it looks.

Try m/(.{40}\n){4}/. It works for me... 

 perl> $" = ''


 perl> $s = ((qq(@{[0..8]}) x 4).$/)x4

 perl> print $s
012345678012345678012345678012345678
012345678012345678012345678012345678

012345678012345678012345678012345678

 perl> print 'Matched'.$/ if ( $s =~ m/(.{40}\n){4}/ )


 perl> $s = ((qq(@{[0..9]}) x 4).$/)x4

 perl> print $s
