Thats a matter of interpretation, the behaviour of push @arr, "elem" can be reproduce with prototypes sub name (\@@)

The prototype is just syntactic sugar for taking a reference (plus extra behaviour, for example enforcing list context), so independently of what it looks like on the caller side, the callee always sees a reference, never the array itself.
