It shouldn't be because the examples under that particular heading demonstrate how variables can be used to express the definition of an anonymous set. They are effective at the point that they are incorporated by a rule. All variables require the use of the $ sigil to be referenced, which is somewhat akin to parameter expansion in the shell. The @ sigil is used for matching sets that are formally defined and named by the use of the set keyword.
