Hi,
I can't make it out how to do the arity transformation for proto::functions varargs too. Could anybody shed some light?
I think I may need more information about what you're trying to do. There is a (rather advanced) example of using the fold transform on a proto::function with varargs here: http://tinyurl.com/2l9srv. Does that help any? When dealing with varargs, the fold and reverse_fold transforms are especially handy because they iterate over the sequence of children nodes for you -- you don't have to worry about how many there are. So if you can express your transform using fold, it'll make life easier. -- Eric Niebler Boost Consulting www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
