Thanks.
I'm beginning to think the declaration is a bit ugly though. How about
something like this instead:
%destructor { free ($$); } %symbol-default
%printer { fprintf (yyoutput, "%s", $$); } %symbol-default
I think that's clearer than just an empty list. Unfortunately, it is yet
another % declaration, but it may have other uses: see here where I called
it %any instead:

What do you think?
