Is this warning still valid?

The @property thing doesn't do much. All it does is change typeof(a.prop) from function over to the return value of the function. (Which actually makes it required for the range empty and front things!)

It's not required:

    struct Example
    {
        int front() { return 42; }
        bool empty() { return false; }
        void popFront() {}
    }

    import std.range;
    static assert(isInputRange!Example);
