Hello,

I'm trying to modify the Player example and to separate the on_exit/on_entry
template function definition from declaration so I can hide the actual
implementation details. 

"My.h"
...
namespace myNamespace
{
       ...
       // Concrete FSM implementation
       struct player_state_machine : public msm::front::state_machine_def
       {
              ...
              struct Playing : msm::front::state<>
              {
                     template 
                     void on_entry(event const &, player_state_machine  & );
// { "My Secret Code }
              }
              ......
       }
}

"My.cpp"

namespace myNamespace
{
    ...
    template 
    void myNamespace::player_state_machine::Playing::on_entry(Event const &,
player_state_machine & );         
    { 
     Here I want to put the actual implementation...
     }

Is this feasible ?
If not - what are the alternatives ? As I previously said - putting the
implementation into the header is not an option.

Any help will be appreciated.

Evgeni
