Excuse dumb question about lambda calculus. I'm using a typed lambda calculus for a kinding system (the types are TYPE, TYPE->TYPE etc). I'm uncertain how to handle recursion though. Example: list a = 1 + a * list a or list = fix f . fun a. 1 + a * f a now we need: list int = 1 + int * list int or list int = fix x . 1 + int * x which suggests the following reduction: fix f . fun x . e ==> fix z . e [f x -> z] Well, the rule works in this case. Will it always work? -- John Max Skaller, mailto:skaller@ozemail.com.au snail:10/1 Toxteth Rd, Glebe, NSW 2037, Australia. voice:61-2-9660-0850 ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
