is_actor is defined as:

namespace boost { namespace phoenix
{
///////////////////////////////////////////////////////////////////////////////
//
//  is_actor<T>
//
//      Tests if T is an actor. Evaluates to mpl::true_ or mpl::false_
//
///////////////////////////////////////////////////////////////////////////////

     template <typename T, typename Enable = void>
     struct is_actor
         : mpl::false_
     {};
}}

At the moment it is not really used internally by phoenix. But it is 
used by, for example spirit.
