Absolutely true. And the worst thing you can do when you really can't
avoid pointers is to obscure the issue even more by disguising them as
something else.

The biggest problems with pointers relate to things with pointer math,
pointers to deleted objects etc. These things need not exist in a
scripting language that provides pointers - pointers don't have to be
implemented using store addresses. That is just a concept from C, C++,
Pascal, Ada etc - not something I want to see imitated. If pointers
can be created that refer to given objects, and if pointers can be
dereferenced, that is actually enough to support indirect referencing.
