Is outer quoting not needed (docs say "redundant")?

[Sebastian Gniazdowski <psprint@xxxxxxxxxxx>]

Hello,
manual says:
"in "${(@f)"$(foo)"}", there are two sets  of quotes,  one  surrounding  the whole expression, the other (redundant) surrounding the $(foo) as before."

One user reported that single, outer quoting always worked for him. Word "redundant" quite confirms this, but can we be sure? Nevertheless, I'll add a note to my handbook, will not replace example, because it well showns that quotings don't e.g. cancel each other (on the other hand, inner quoting doesn't have a real role, hm).
