[Boost-users] how to create a tuple from an mpl sequence?

I've got some mpl sequence from which I want to create a tuple. Anybody any clue? I also looked into fusion (why is there so much overlap to mpl?) but did not find anything. Tried fusion::result_of::push_back without much success. Tried fusion::vector with fusion::result_of::push_back . Does this functionality exist? Peter
