    //  Summary:
    //  A semantic action policy holder. This holder stores a reference to ref
    //  and a const reference to value_ref.
    //  act methods are feed with ref and value_ref. The parse result is
    //  not used by this holder.
    //
    //  (This doc uses convention available in actors.hpp)
    //
    //  Constructor:
    //      ...(T& ref_, ValueT const& value_ref_);
    //      where ref_ and value_ref_ are stored in the holder.
    //
    //  Action calls:
    //      act(ref, value_ref);
    //
    //  () operators: both
    //
