What I really want is a Haskell-like persistent (i.e. purely functional) dictionary implemented as an AVL tree or something like that. It means the "child" can just be a forked version of the parent, that shares most of the same nodes. I think that handles most of the obvious uses of the nested mapping proposal. Hedgehog Lisp has AVL-based persistent dictionaries implemented in C, that I've been thinking of trying to port to the Python C API sometime. -- http://mail.python.org/mailman/listinfo/python-list
