Something like that sounds reasonable.

I assume that %param and YYPARSE_PARAM would be incompatible?  I.e., a
grammar wouldn't be able to use both features, and YYPARSE_PARAM would
be deprecated but would be supported for a while, so long as the
grammer doesn't also use %param.

What about YYLEX_PARAM?  Perhaps we want %parse_param versus %lex_param?
