Which functional programming language(s) should we teach?
Laurie Dillon just posted the SIGPLAN eduction board article on Why Undergraduates Should Learn the Principles of Programming Languages to our faculty mailing list at the MSU Computer Science department. One question that came up in the ensuing conversation was: what functional programming language(s) would/should we teach?
I mentioned OCaml, Haskell, and Erlang as reasonably pure but still pragmatic FP languages. Anything else that's both "truly" functional and used somewhat broadly in the real world?
