// 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
