Not really, no. Like Elm, it strips away practically everything that wasn't already in 1970s-era ML. It's much closer to a trimmed-down Ocaml than it is to Haskell.
Not just the ML community. Go's simplicity is often derided, but I think the best in class tooling (dev tooling like gopls, golangci-lint, deployment tooling like ServiceWeaver, Goreleasor, etc) and easy understandability more than make up for "what yuu can't do"
Not just in the Go community! Everyone believes in "as simple as possible". The disagreement is about "but no simpler".
Given its strict purity and use of typeclasses over modules I would say roc is more like haskell than it is ocaml.
