Hi, everybody. I reimplemented the function isa? in terms of a protocol Is-A.
The reason why you would want to do that is in the README at https://github.com/leifp/clj-isa-protocol tl;dr: One of the reasons why people are excited about predicate dispatch is the irritation caused by the dispatch function of a multimethod being closed. You have to decide up front what information the dispatch fn is going to pull out of your arguments. Changing it afterward is a pain. Since the dispatch uses 'isa?' internally, if that function is extensible, then multimethod dispatch becomes, to a certain extent, open. See the README. Comments, critique, code, and questions welcome. Cheers, Leif P.S. As an aside to people that like weird, obscure programming languages, the rough idea of how is-a? should work for maps was inspired by (but very much simpler than) the functional logic language LIFE [ http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.90.3175 ] -- You received this message because you are subscribed to the Google Groups "Clojure" group.
