    /** Generic functor for expanding a range with a number of other
        ranges.

        Since *Range::expand() is overloaded, straight-forward
        application of ::boost::bind and friends fails (because of
        ambiguities). Thus, this functor template can be used, to
        expand the given range with a number of other ranges, passed
        in at the function operator.

        @tpl RangeType
        Range type to operate with. Preferrably, one of B1*Range,
        B2*Range, or B3*Range.
