[Boost-users] How to get tuple member type ?

Hello I have constructed a type of STL containers and tuples in my prgogram, and even though I have a typedef for it, when I use it I often need the inner types involved. Now STL has the value_type declarations for all containers, but for tuples is there a documented way to get the type of a tuple member ? Or the type of the tuple<>::get<>() function ? Thank you, Timothy Madden
