How can I write a grammar that accept a given set of terminal and
functions with up to N arguments
(for example accepting function with 1 to 5 arguments but not 6 or more) ?
I believe i can count the elements of vararg using mpl::size ons ome
proto::arg_ or proto::value maybe
but how to prevent those who violates this condition be removed from the
accepted functions et ?
thanks in advance
