27     //  A semantic action policy holder. This holder stores a reference to ref.
28     //  act methods are feed with ref and the parse result.
29     //
30     //  (This doc uses convention available in actors.hpp)
31     //
32     //  Constructor:
33     //      ...(T& ref_);
34     //      where ref_ is stored.
35     //
36     //  Action calls:
37     //      act(ref, value);
38     //      act(ref, first,last);
39     //
40     //  () operators: both
