       - **Unit tests**: As stated before, `Reflection` is not supported and because NUnit 
         uses this approach to execute the test, then it will not work either. This makes

         runtime and not compile time.

   * A few words on the `SandboxBuilder` works:
      - The library is build on top of the [AppDomain Class][appdomain] which 
        allows to [Run Partially Trusted Code in a Sandbox][sandbox]. The 
        `SandboxBuilder` is only allowed to execute code
        `(SecurityPermissionFlag.Execution)`, which is the minimum permission that
  
negative.code:       (`Delay : f:(unit -> 'a IOEffect) -> 'a IOEffect`), which tries to evaluate
        the function at the newly created domain (`AppDomain`) with the minimum
        granted permision instead of the executing `AppDomain.CurrentDomain`.
        If the function evaluation is successful then an `IOSafe 'a` value is returned, 
        otherwise an `Unsafe` `Exception` is returned.
      - In order to ensure that `IOEffect` types are only instantiated from inside
        the computation expression, a few examples: `IOSafe "42"` or
