Nah, never used for that. Well, except for the bits of parrot written in

I can think of a number of different ways to do this. Different behaviour
based on assignment/read types (integer read/write get/set the pointer
address, string read/write get/set the data pointed to) would probably be A
Bad Thing. Also what I'd be likely to do, but I think we've already
established I do Bad Things. :)
A method to change the address would probably be the best thing.
