   To quote from K&R, appendix A, section 8.2, "Type Specifiers":

       If the type-specifier is missing from a declaration, it
       is taken to be int.

   This seems like one "feature" we could afford to lose (IMHO).

   How, (I'm sure you'll tell me :-), do you (does the compiler) tell:

                 WhatAmI , AndMoreVariables ;
                    |    |      \
                  expr. comma   expression
                       operator

   from:

                 WhatAmI , AndMoreVariables ;
            |       |    |      \
         assumed  ident comma  identifier
	 type int
