My little experiments with OCaml have been pleasant thus far (in terms of language ergonomics), but on the tooling side Haskell (or rather I should say GHC) is pretty sweet. For what I had to do thus far, at one point I needed to step debug through my code. Whereas in GHC land I reload my project in the interpreter (GHCi or cabal repl), set a break point on function name and step through the execution. With OCaml I have to go through the separate bytecode compiler to build it with debug symbols and the I can navigate through program execution. The nice thing is that I can easily go back in execution in flow ("timetravel debugging"), but a less ergonomic. Also less experienced with this flow, to consider my issues authoritative. I don't have that much experience with dune (aside from setting up a project and running dune build), but one thing that confused me at first, is that the libraries I have to add to the configuration do not necessarily match the Opam package names. The LSP is fast, as mentioned before, it supports goto definition, but once I jump to a definition to one of my dependencies I get a bunch of squiggly lines in those files (probably can't see transitive dependency symbols, if I where to guess). I can navigate dependencies one level deeper than I can with the Haskell language server, though. I actually want to better understand how to build my projects without Dune, and probably will attempt to do so in the future. The same way I know how to manage a Haskell project without Cabal. Feels like it gives me a better understanding of the ecosystem.
