This one works:

----
struct Stack(T) {
     T[] stack;
     alias stack this;
     bool empty() {return empty(stack);} /* not using UFCS */
     import std.array: empty; /* has to come after the method */
}
----

Looks very much like a compiler bug now. As far as I know, the order of 
declarations shouldn't have an effect like that in structs. And UFCS 
should also be ok there, as far as I can tell.
