The same way, you could have some dependencies with `yield` and some other dependencies with `return`, and have some of those depend on some of the others.

And you could have a single dependency that requires several other dependencies with `yield`, etc.

#### Pushes

A push occurs when Istiod detects an update of some set of configuration is needed. This results in roughly the same result as a Request (new configuration is pushed to the client), and is just triggered by a different source.

   * the source or written to the sink. Typically, this will just return the input directly, but in
   * some cases it may alter the input. For example, if the factory returns a sliced view of a
   * source created with some given bytes, this method would return a subsequence of the given
   * (byte[]) data.
