I'm not convinced that Base will solve our problems. It's not, afaik, more portable, more lightweight, more performant, or more feature-full than [containers](https://github.com/c-cube/ocaml-containers https://github.com/c-cube/ocaml-containers) (which has reached 1.0 and also does a bit of IO and Unix, as a stdlib extension). In addition to that it's not compatible with programs that use the stdlib right now, so the fragmentation will stay for a long time (unlike for build systems where you "only" have to change the build scripts, not the code itself). (Of course I'm biased too, I wrote containers ^^)
