And I think I've uncovered yet another bug:

class A 
{
    int slowFunc(int a, int b) 
    { 
        int result;

        /* Error: function expected before (), not mixin memoize!(slowFunc)
fastFunc; */
        if (a > 1)
            return fastFunc(a-1, b);

        return result;
    }

    mixin memoize!slowFunc fastFunc;
}

If I replace 'return fastFunc(a-1, b);' with 'return this.fastFunc(a-1, b)' it
works.
