I've been playing with Boost's tuples library, but I'm having some trouble working through a wrinkle: I have some routines that use tuple<int>, tuple<int, int>, etc., up to tuple<int, int, int, int, int>. I'd like to be able to declare these objects using an alternative notation, along the lines of: tuple_clone<int, 1>, tuple_clone<int, 2>, tuple_clone<int, 3>, etc. The objective would be to allow me to write a function template that looked something like this: template <int N> tuple_clone<int, N> fn(tuple_clone<int, N-1> t) { tuple_clone<int, N> ret; ret.get_head() = getValue(); ret.get_tail() = t; return ret; } Each time I try to write tuple_clone, though, I end up stumped. Is it possible to write something like this, while leveraging the tuples library? Or is there a different approach I ought to look into?
