    initial v1  
    11The following code, as deque_convert.cpp, which uses the generic boost::fusion::convert to convert to a boost::fusion::deque, fails with a compiler error:

    92109I discovered this bug testing out a PR for the iterator library where a suggested change has been implemented so that the zip_iterator in the iterator library can use fusion sequences, and through the fusion adapter, std::tuple, as the tuple type for the tupleiterator of a zip_iterator.
