      That is not an array, but an array reference.

        That is not an array, but an array reference.

        And what do you call this "array reference", what is the name of the array it refers to ?

    @{ $whatever } de-references the array ref $whatever so you can use the reference as an array. Your data are contained in array references which you need to de-reference with @{ } to use as arrays.
