I am not sure that I understand the suggested approach here.

The parser actually now works with a partial input, it just happens to
be that instead of returning EOF at the end it returns the following

	GENERATE_COMPLETION <- This must be handled individually by 
	 			each completion-aware production.

	COMPLETE_COMPLETION <- An infinite stream of these to help yacc
				produce a valid AST.  Handling for these
				are required on all productions that
				might participate in a partial tree,
				and this will require an ongoing effort
				to make it perfect.

	EOF		    <- This merely completes the parsing process
