The `@` symbol is a variable by itself, what is very clear from it's name, even more because `$` certainly isn't and I also don't think `%` is one (that last is for dictionaries, by the way).
Another system defined variable is `$_`, that is as well named as the one I cited.
There are many more of those in Perl, but I can't remember them for some reason.
