/**
 * @assertion Future.sync(dynamic computation())
 * Creates a future containing the result of immediately calling computation.
 * If calling computation throws, the returned future is completed with the
 * error.
 * If calling computation returns a Future, completion of the created future
 * will wait until the returned future completes, and will then complete with
 * the same result.
 * If calling computation returns a non-future value, the returned future is
 * completed with that value.
 * @description Checks that computation() is done synchronously.
