    //  Summary:
    //  A semantic action policy holder. This holder stores a reference to ref.
    //  act methods are feed with ref and the parse result.
    //
    //  (This doc uses convention available in actors.hpp)
    //
    //  Constructor:
    //      ...(T& ref_);
    //      where ref_ is stored.
    //
    //  Action calls:
    //      act(ref, value);
    //      act(ref, first,last);
    //
    //  () operators: both
    //
