A lot of the classes have macros like this:

    BOOST_IOSTREAMS_FORWARD( code_converter, open_impl, Device,
                             BOOST_IOSTREAMS_CONVERTER_PARAMS,
                             BOOST_IOSTREAMS_CONVERTER_ARGS )

These generate constructors with different numbers of arguments which
are forwarded to the implementation object. The problem is that since
they're template based they're often a better match for arguments than
the constructor you actually want to use.
