I'm tempted to say just cast it away, since you aren't actually
breaking purity in any meaningful way; the return value is always
the same and it should have no other side effects (except on the
internal variable).


Lying around pure was a bit of a pain... but this seems to have
done the trick:

alias pure string function () hax;

private string impureConstructor() {
        static string cache;
        if(cache is null)
                cache = "lol pure defeated";
        return cache;
}

private pure hax getPureConstructor() { return cast(hax) 
&impureConstructor; }

public @system @property pure string test() {
        return getPureConstructor()();
}


// test now works
