18    //  Summary:
19    //  A semantic action policy holder. This holder stores a reference to ref
20    //  and a const reference to value_ref.
21    //  act methods are feed with ref and value_ref. The parse result is
22    //  not used by this holder.
23    //
24    //  (This doc uses convention available in actors.hpp)
25    //
26    //  Constructor:
27    //      ...(T& ref_, ValueT const& value_ref_);
28    //      where ref_ and value_ref_ are stored in the holder.
29    //
30    //  Action calls:
31    //      act(ref, value_ref);
32    //
33    //  () operators: both
34    //
