FWIW, F# has "using". Between "using" and IDispose, you've got all the resource-unlocking, unwinding, and rollbacks you'd ever want.

I think this article makes it very clear how having a huge existing set of libraries can really put a language into warp drive, whereas not having one means you are going to spend some time re-inventing the wheel. (But even in straight Ocaml, I fail to see the problem)
