safe
     
        A safe program analysis is one which will not reach invalid
        conclusions about the behaviour of the program.  This may
        involve making safe approximations to properties of parts of
        the program.  A safe approximation is one which gives less
        information.
     
        For example, strictness analysis aims to answer the question
        "will this function evaluate its argument"?.  The two possible
        results are "definitely" and "don't know".  A safe
        approximation for "definitely" is "don't know".  The two
        possible results correspond to the two sets: "the set of all
        functions which evaluate their argument" and "all functions".
        A set can be safely approximated by another which contains it.
