My reason for mentioning OS-level filesystem was to show that even in that limited domain, treating paths as strings leads to bugs.

However, I was discussing the use of "/" to invoke path composition, which is a computation. Nobody will use that for communication (except to describe a path expression in graph theoretic terms), and I don't think it's a good idea to use that particular symbol for that operation. -- School of Systems and Information Engineering http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
