It seems that input array is always passed by reference.
For example if you have an existing array
$array with some values
then you have an arrayobject $o
and then you do this:
$o->exchangeArray($array);
$o->offsetSet('somekey', 'some value');

Now if you check your $array array, it will have
a key 'somekey' with value of 'some value'

I totally did not expect that, I am sure it was a mistake to pass array by reference by default.
