How do I compile and run third party code snippet in Haskell securely?

Question

userDefinedFunction = "\x -> x*x :: Int"
main = do
    f <- complileFunction userDefinedFunction :: Int -> Int
    let results = map f [1,2,3,4]
    print $ show results

How to do it securely? userDefinedFunction is supposed to be untrusted third-party code. It should be built to fast, optimized code, but should not be able to access system directly.

I suppose it should combine Safe Haskell and System.Eval.Haskell. Are there any projects or tutorials covering this?

There is a wiki page for exactly this use case You could also have a look at lambdabots source code.
