The proposed solution allow you to pass a Callable without arguments and 
don't returning anything (void(void)). Using lambdas or std::bind you 
are able to call any function with a variable number of arguments.

|     loop.postTask([]{foo("task",  0);});

or

||     loop.postTask(std::bind(foo,"task",  0));
|

What you don't understand? Are you looking for

|     loop.postTask(foo,"task",  0);
|

?

In this case you need to forward these arguments to bind

       template <typename F, typename ...Args>

|     void  postTask(F&& f, Args&&... args)
     {
         std::lock_guard<std::mutex>  lock(m_Mutex);
         m_Tasks.push(std::bind(std::forward<F>(f),|||std::forward<Args>(|args)...));
     }|

or something like that.

Best,
