Personally I am not a fan of namespaces in picolisp. However, once there is support for namespaces, as Christian points out, there are other operations that should be supported. It seems to me that your suggested implementation solves the problem of symbol name clashes, but introduces a new problem of namespace name clashes. Do I read that right? One of the most important operations on namespaces should be creating a local name (alias) for it. Common Lisp didn't get this right, for example, so it would be great if picolisp avoided that flaw.
