      Ok Thanks. I was looking at the specializations and didn't even see the enable parameters.

Thanks so much for the help. A couple more questions:
1) Is it possible to add an enable parameter to is_actor in futureversions 
of phoenix?
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 
    struct is_actor
        : mpl::false_
    {};
}}
...
2) Is the is_actor trait used internally by phoenix? The reason I ask is I 
am thinking
 about using my own is_actor trait for my extended actors unitl maybe this 
gets updated
 in boost.
At the moment it is not really used internally by phoenix. But it is used by, 
for example spirit.
