So what's the difference between $array and @array then?
$ indicates that a variable will behave as if its content were a singular thing. That singular thing could be a number, string, routine, object, etc. -- or an array or hash. In list context its content will evaluate to be a singular thing; if it's actually plural, that singular thing will be a reference to the plural thing.
@ indicates that a variable will behave as if its content were a plural thing. If the content is actually singular it behaves like a 1 element array.
