clojure does not have lazy evaluation of any form. “lazy sequences” are a hack, clojure core uses macros to thunkify sequence traversal in userland. this hack interacts badly with a few other aspects of clojure because clojure itself is not lazy, being that it is a hosted language designed to lightly cover the host platform (Java, JS, .NET, Dart) and maximize host ecosystem compatibility and therefore does not alter core platform semantics such as concurrency model or evaluation model.
