Usually, when you want a hashreference, you use the $ prototype. After all, a hash reference is a scalar. The prototypes \% and \@ are special. It means that a variable in that slot has to start with a % or a @, and that the hash or array will not be flattened out. You would use this to prototype functions with a similar behaviour as keys or push.
