| /** |
| * @assertion Future(dynamic computation()) |
| * Creates a future containing the result of calling computation |
| * asynchronously with Timer.run. |
| * If the result of executing computation throws, the returned future is |
| * completed with the error. |
| * If the returned value is itself a Future, completion of the created |
| * future will wait until the returned future completes, and will then |
| * complete with the same result. |
| * If a non-future value is returned, the returned future is completed with |
| * that value. |
| * @description Checks that computation() is run asynchronously. |
