In a system that really embraces the random-access pair type as fundamental, these would just be identities.I think this would be good: otherwise programs would not be able to portably exploit systems that embrace random-access lists.
In a system that uses random-access lists everywhere, you would not need conversions. In a system that doesn't, these are easy to portably define. So now I'm not sure what your concern is.
