This is even much more safe than relying on a language (which can have conceptual and/or implementation bugs) alone. The attack surface of any non-trivial language, its implementation and its runtime is just too big for anything serious. Sandboxes are complex, too, but less so, and you implement them once and you can use them for many things. Having said that, my personal view is that Safe Haskell has almost no valid use case anymore, given the various sandboxing technologies available today.
