/// This file contains the declaration of the SYCL async_handler type, which
/// is a callable, such as a function class or lambda, with an exception_list as
/// a parameter. Invocation of an async_handler may be triggered by the queue
/// member functions queue::wait_and_throw or queue::throw_asynchronous, by the
/// event member function event::wait_and_throw, or automatically on destruction
/// of a queue or context that contains unconsumed asynchronous errors.
