* @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 some integer value, then type error
* is arisen in checked mode or returned Future instance completes with error
* otherwise
* @compile-error
