This is for those people who do not like OCaml because of those warts. If you are one who is already sold on OCaml, it's very easy to forget how many there really are.
Regarding "Build Systems Rapidly": Please hang in there and stay tuned. The syntax is there to help people learn ML rapidly. The Merlin integration and syntax formatting tooling is there to help people become productive rapidly inside their editors. Next, we have specified a workflow for actually building systems rapidly (as in compiling large projects with namespacing rules).
Instead of our previous approach where we just drop a more polished project with many of the goals accomplished, this kind of project benefits from expertise that is distributed across the entire industry and for that, it's better to be open earlier. I hope you can appreciate and encourage this kind of openness.
