I think a lot of people that come from clojure arrive at consensus that you can instrument some typechecking on edges. Define what is valid(input) data and move it through your program. Inside your program it rarely matters(from validity perspective) if something is a list, tuple, lazylist - it is a collection. Things are either single value, collection or associative the semantics around each in code are pretty obvious in most cases. Its always contentious topic, there are no answers.
