/**
 * @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.
