initializing a closure variable

[Kevin Pfeiffer]

Hi Perlers,

I would have thought that this would initialize my $indent variable to 2
(like setting an initial state for an object), but if I call "indent()" I
get nothing back. :-(


{  # static local variable
   my $indent = 2;

   sub indent {
      my $increment = shift;
      $indent += $increment if $increment;
      return $indent;
   }
}

-Kevin
