Maybe not fully, but you can do a lot more with them than you can in Pascal or Modula-2.
- Containers of references are not allowed.
You can't have arrays of references, but struct and class members can be references, so you can certainly build data structures that contain them. (A quick experiment suggests that you can even have arrays of structs that contain references, so I'm not sure why they're not allowed in arrays directly.)
- Once a reference to an object is created, it cannot be changed to reference another object ("to be reseated").
Actually there is a way to do that, but you have to be sneaky about it. Greg -- https://mail.python.org/mailman/listinfo/python-list
