Could we say "not for beginners"? I mean, it has legitimate uses. If we say "not recommended", people will remember it as non-beginners and avoid it, even when it is exactly the right thing to do. Also, the text could be "left assignment in outer lexical scope" to avoid the somewhat vacuous reference to "the environments".

Also on pkg::foo(), I'd say "not usually required" or "only needed if two packages contain the same function".
