   Fortran 2008 rule R1214

   proc-decl is procedure-entity-name [ => proc-pointer-init ]

   where (R1216) proc-pointer-init is either null-init or
   initial-proc-target, and (R1217) initial-proc-target is a
   procedure-name. The Fortran 2003 form of R1214 only accepts
   null-init on the right-hand side of ``=>``; this subclass
   extends it to also accept an initial-proc-target so that
   declarations such as::

       procedure(cb), pointer, nopass :: eval => dummy

   parse under ``std='f2008'``.

   .. py:method:: match(string: str) -> Optional[Tuple[fparser.two.Fortran2003.Procedure_Entity_Name, str, Union[fparser.two.Fortran2003.Null_Init, fparser.two.Fortran2003.Name]]]
      :staticmethod:


      Attempts to match the supplied text with this rule.

      Calls the Fortran 2003 match first (which handles the
      null-init branch); if that fails, tries the Fortran 2008
      initial-proc-target branch where the right-hand side of
      ``=>`` is a procedure-name.

      :param string: Fortran code to check for a match.

      :returns: None if there is no match, otherwise a 3-tuple
          of (procedure-entity-name, ``"=>"``, proc-pointer-init).
