Hi all I'm trying to implement a particular datastructure in Factor for XML parsing. It's sorta like a circular list. The code is at http://paste.lisp.org/display/35077 . For some reason, it works when I use things like length, nth and set-nth, but >string and sequence= don't work, complaining that there is no length method. Strangely, each and map still do work. Do you have any ideas for how to fix this or what the problem is? Chris thought it might be something related to delegation, but that isn't true, because no delegation is used. He said that the code actually works if you step through nth-unsafe in the walker. Is there an error in what I've written, or possibly in the implementation of generic words?
