Yes, but MyClass provides the method __toString() which allows it to be
used *like* a string. When asked for, MyClass will just return a string
representation of itself as the return value of its __toString() method.

However - there is no __toArray() method to rturn an array when needed.
That's the reason why ArrayObject provides getArrayCopy() to get a copy
of the array object as an array value.
