Yep, sorry for the M-t, but actually it is thanks to the sed snippet
that I finally understood your point.  I thought you wanted that
yyparse take care of freeing the %parse-params!  And indeed, it made
little sense :)

But it seems that you are pointing out a bug: when I made
%parse-param, I had very clearly in mind that it should be available
everywhere where user code is called.  That's what happens in C++, for
free (since these are members).

We need no %destructor-param etc., we need to fix yydestructor and
yysymprint so that %parse-param are passed to them, just like yyerror.
