In which case it makes sense, as I'm sure Larry has said at some point in the past, just to think of the sigils as part of the name. $a[4] and @a[4] do the same thing. If you want to think of $a[4] as doing some dereferencing, feel free. They're both extracting an element from an array object. If a "scalar" variable can hold an array object, then it isn't very "scalar"; the sigils don't have much semantic value. -- As usual, this being a 1.3.x release, I haven't even compiled this kernel yet. So if it works, you should be doubly impressed. (Linus Torvalds, announcing kernel 1.3.3 on the linux-kernel mailing list.)
