I don't know what's going on here. The error message doesn't make sense to me. Might be a bug in the compiler.

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.

struct Stack(T) {
    import std.array: empty;
    T[] stack;
    alias stack this;
    bool empty() { return empty(stack); }
}

void main()
{
    Stack!int stack;
    //bool x = stack.empty; // fails
    bool x = stack.empty(); // works
}
