I second Rich's excellent suggestion.
As with all elegant solutions, Iris's clicked on the wee light bulb in

more enlightening, alternative may be:
z |> attr("names") |> _[2] <- "foo"
However, I would add this as an example *only with* Iris's solution.
Hers should be shown whether or not the above is.
Cheers,
Bert
