[Boost-users] [Fusion] Flatten a sequence of sequences

Hi All Lets say I have something like the following: make_vector(1, make_vector('b', 3, make_vector(4, 5.5), "six"), 7, 8) I want to produce an function f such that f(make_vector(1, make_vector('b', 3, make_vector(4, 5.5), "six"), 7, 8)) -> [1,'b',3,4,5.5,"six",7,8] i.e. a flattened version of the sequence. I don't mind if this is a view of the original sequence or an actual vector. I don't mind a solution in C++0x if it can compile on GCC 4.5.1. Thanks
