I don’t know OCaml, or really any language that would help me fully understand the code, but my exposure to OCaml is this stuff, and it looks pretty clean to me. https://github.com/janestreet/base Of course, I haven’t read every file, so maybe I got lucky with my random sampling. |

Excerpt:
> Tradition dictates that Unix system programming must be done in C. For this course we found it more interesting to use a higher-level language, namely OCaml, to explain the fundamentals of Unix system programming.
> The OCaml interface to Unix system calls is more abstract. Instead of encoding everything in terms of integers and bit fields as in C, OCaml uses the whole power of the ML type system to clearly represent the arguments and return values of system calls. Hence, it becomes easier to explain the semantics of the calls instead of losing oneself explaining how the arguments and the results have to be en/decoded. (See, for example, the presentation of the system call wait, page ??.)
> Furthermore, due to the static type system and the clarity of its primitives, it is safer to program in OCaml than in C. The experienced C programmer may see these benefits as useless luxury, however they are crucial for the inexperienced audience of this course.
> A second goal of this exposition of system programming is to show OCaml performing in a domain out of its usual applications in theorem proving, compilation and symbolic computation. The outcome of the experiment is rather positive, thanks to OCaml’s solid imperative kernel and its other novel aspects like parametric polymorphism, higher-order functions and exceptions. It also shows that instead of applicative and imperative programming being mutually exclusive, their combination makes it possible to integrate in the same program complex symbolic computations and a good interface with the operating system.
