The reason that when you add print @$valref{cn}; that you get ARRAY(0x25d9ec4) is
because it is printing the actual reference to the data, not the data. So that means
that ARRAY(0x25d9ec4) is the actual memory location of the data that you are
referencing. If you copy that reference, you will copy the address so that you are
still looking at the same data.
It is similar to pointers in C. The reference "points" to the data in memory, whereas
the variable isn't actually holding the data.
Does that make sense?
