Have you looked at F#? If you like the MLish aspects of Rust but want to not have to deal with some of the manual memory management complexity it's pretty nice. There's access to the whole .NET ecosystem too, as well as really good tooling and IDE support, though not all .NET libraries written in / for C# feel totally natural to consume from F#.

Some of them going forward aren't even possible to consume from F# unless there is a C# shim, e.g. anything that relies on code annoations for code generators, or post .NET 8, interceptors.

OCaml is a much better option in the UNIX world.
