    Doing  textout(byteaout(...  really makes no sense. But being
    able to do a textin(mytypeout(... does  make  sense  for  me.
    Without   that,  there  MUST  be  type  casting  support  for
    MYTYPE->TEXT in the parser.

    Sometimes ppl implement user defined  types.  I  assume  this
    kind  of  type  casting  is  used  somewhere  in  a couple of
    applications.
