I have recently translated the Async code examples from the excellent Real World OCaml into Lwt:
If you have learned (or are learning) Async through RWO and want to know Lwt as an alternative, the translated examples will be able to give you a quick overview of how similar or different Lwt and Async are. I hope they will also be helpful for people who are looking for more code examples in addition to those in the Lwt repository.
Happy hacking with OCaml!
