-    description: Using the `asIndexedPairs` method emits a runtime warning that
-                  it will be removed in a future version.

-> Stability: 1 - Experimental
-
-* `options` {Object}
-  * `signal` {AbortSignal} allows destroying the stream if the signal is
-    aborted.
-* Returns: {Readable} a stream of indexed pairs.
-
-This method returns a new stream with chunks of the underlying stream paired
-with a counter in the form `[index, chunk]`. The first index value is 0 and it
-increases by 1 for each chunk produced.
