Re: [Boost-users] [1.33][tuple] Problem with tuples longer than 10 elements

That is general limitation. The documentation says:

"The current version supports tuples with 0-10 elements."

If you want more and more features I would recommend using
boost::fusion. This is an awesome lib. But your compiler will hate it.
;-)

Let me know if you have more questions.
