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
