While looking at this node, I saw 

  $month=.0.$month;

[download]
and wondered what that leading period was on the number. Is .0 equivalent to 0.0? 
  my $s = 'abc';
  $s = .0.$s;
  print $s, "\n";

[download]
yields 0abc, but then I tried: 
  my $n = .0;
  print $n, "\n";

[download]
which yields 0D, and so does 
  print .0, "\n";

So the newline character is being converted to its ASCII code. Would someone explain this to me please?
