/**
* Asynchronous operations may represent a continuation of the asynchronous
* control flow associated with the current handler. The implementation can use
* this knowledge to optimise scheduling of the handler.
*
* Implement asio_handler_is_continuation for your own handlers to indicate
* when a handler represents a continuation.
*
* The default implementation of the continuation hook returns <tt>false</tt>.
*
* @par Example
* @code
* class my_handler;
*
* bool asio_handler_is_continuation(my_handler* context)
* {
* return true;
* }
* @endcode
