   Hi Folks,   
      
   The Flex manual says this:   
      
       Pattern-matching of NULs is substantially slower   
       than matching other characters.   
      
   Why is that?

   [My recollection is that zero is used as a flag value in internal   
   tables and there is some slow kludge to say that this is a nul not the   
   flag, but perhaps someone who has looked at the code more recently   
   will remember the details. -John]
