Hi
That is general limitation. The documentation says:
"The current version supports tuples with 0-10 elements."
OK. I did not find that.
If you don't mind using a more cumbersome notation, cons lists can be used to circumvent this limitation: http://boost.org/libs/tuple/doc/tuple_advanced_interface.html For instance: #include <boost/tuple/tuple.hpp> struct T0{}; struct T1{}; struct T2{}; struct T3{}; struct T4{}; struct T5{}; struct T6{}; struct T7{}; struct T8{}; struct T9{}; struct T10{}; struct T11{}; struct T12{}; struct T13{}; struct T14{}; struct T15{}; typedef boost::tuples::cons<T0, boost::tuples::cons<T1, boost::tuples::cons<T2, boost::tuples::cons<T3, boost::tuples::cons<T4, boost::tuples::cons<T5, boost::tuples::cons<T6, boost::tuples::cons<T7, boost::tuples::cons<T8, boost::tuples::cons<T9, boost::tuples::cons<T10, boost::tuples::cons<T11, boost::tuples::cons<T12, boost::tuples::cons<T13, boost::tuples::cons<T14, boost::tuples::cons<T15,boost::tuples::null_type
