It means that it used to be that you could modify the internals of
an object by doing something like:
change skip first object 5 'foo
Now, since 'first object' is a reference to a copy of object's words and
not a direct reference to object's words, it isn't possible anymore.
This closes a small hole of opportunity for buffer overrun types of
security hacking and prevents messing around with object and function
internals.
