I always wonder if I just showed up late when I hear about the ecosystem! I just get opam for packages, dune for building, and merlin for editor integration (I did pay the complexity task using a language server for neovim, but merlin integrates with vim pretty trivially). It was easier than setting up Java + mvn|sbt|whatever + Intellij, easier than Python... there's maybe more going on than Go because the tools aren't all in one distribution, but man are the returns over Go massive (for the things I value).
