  The argument values supplied to a PL/Perl function's code are
   simply the input arguments converted to text form (just as if they
   had been displayed by a
  
   SELECT
  
  statement).
   Conversely, the
  
   return
  
  and
  
   return_next
  
  commands will accept any string that is acceptable input format
   for the function's declared return type.
