Once you are used to working with references, they no longer complicate argument passing. An array reference is always a single scalar while the underlying array may be any length. Passing a reference can take significantly less time.
Alright, but what is the reason for less time when you pass the ref? I always thought the perl optimizes by sending the ref even if you use a direct array.
When you pass an array, Perl *copies* the array elements to @_, so you get two instances of the data in memory.
Where can i find more detailed info?
