The issue is that it tries using [] on the item to see if it defines a range-like thing. Since you don't define opSlice(), it automatically goes to the subrange.This breaks for int[] as well as Array. If I add opSlice to your code (and return this) it works. This is definitely a bug, it should try range functions before opSlice. Please file.
