I wouldn't consider '@' to be a sigil any more than I would a unary minus.
Nonetheless, Perl folk do use that term, specifically.
"One thing that distinguishes Perl from other languages is its use of sigils; the funny looking symbols placed in front of variable names. "
$ Scalar $foo
@ Array @foo
% Hash %foo
& Subroutine &foo
* Typeglob *foo

Perl scripts are also easy to read (for people who have bothered to learn Perl!) because the nouns stand out from verbs. And new verbs can be added to the language without breaking old scripts.
