object description rotation

This suggestion was made to me:

Another thing that would be handy would be some kind of list manager like in TADS or Inform that would make it easier to make things that change descriptions every time you look at them. For example:

long_desc

{

    rotate( "It's a door.", "It's still a door.", "Stop looking at it." )

}

Now, traditionally, you would do such a thing with code like this:


But, of course, sure, some helper routines could be written for anyone who wants the functionality of the suggestion above.  Following is some example code for doing such a thing.  I guess I could add it to Roodylib if enough people think it'd be useful.


And examples of objects that use these would look like:


So, yeah, let me know if you guys want it in Roodylib or what.
