For the Python ‘dict’ type, yes. I already know that I don't want that type, I want a custom mapping type which matches keys according to the algorithm I specify. So, I'm not asking “how do I make ‘dict’ do this?”. I am instead asking “how do I implement a custom type which can duck-type for ‘dict’ but have a different key-lookup implementation?”. -- \ “As the most participatory form of mass speech yet developed, | `\ the Internet deserves the highest protection from governmental | _o__) intrusion.” —U.S. District Court Judge Dalzell | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
