/// @assertion Future<Isolate> spawn(void entryPoint(message), message,
/// {bool paused: false, bool errorsAreFatal, SendPort onExit, SendPort onError})
/// The argument entryPoint specifies the entry point of the spawned isolate.
/// It must be a top-level function or a static method that takes one argument -
/// that is, one-parameter functions that can be compile-time constant function
/// values. It is not allowed to pass the value of function expressions or
/// an instance method extracted from an object.
/// The entry-point function is invoked with the initial message. Usually
/// the initial message contains a SendPort so that the spawner and spawnee can
/// communicate with each other.
/// ...
/// Returns a future that will complete with an Isolate instance if
/// the spawning succeeded. It will complete with an error otherwise.
/// @description Checks that if entryPoint is top level function without
/// arguments, then compile error is arisen
/// @issue #26588
