/// @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.
