Fixed for the next beta, though the correct syntax is:

   function 200,200 {
      pattern {
         pigment_pattern{P}
      }
   }

Also, note that you could (and should) do this instead:

   function 200,200 {
      pigment{P}
   }

I did "fix" it, but simply for language consistency... not because the
feature was really necessary.
