Yes, I agree that things are going in the right direction.

But a lot of things I'm trying to use aren't quite there yet. You mention jbuilder and the generated .merlin... it just doesn't work with current opam packages (at least not with ppx - I'm not doing anything fancy, just basic project with core). To fix this, I had to learn about opam pinning features, and then I had to carefully choose the jbuilder commit that works (the one after the bug has been fix, but before it breaks the compilation of bin_prot that I also use) and so on... As for Merlin, it's great, but the documentation is minimal. When it doesn't work as expected, it's hard to find where to look.

Core and Async are great, but besides 'Real World OCaml' that is a bit outdated and insufficient, there is little documentation and not much help on Stack Overflow.

That being said, I'm not complaining and I'm grateful to the guys developing these tools. But I think newcomers should expect some difficulties if they want to do anything serious using these most recent tools.
