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: 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.
