--file: a.d--
module a;

class A {
    private int[][int] n;

    public int[][int] foo() {
        return n;
    }
} 
-------------
--file: b.d--
import std.stdio;
import a;

int main() {
    A a = new A();
    if (a.foo().keys.length != 0) {
        foreach (key, value; a.foo()) {
            writefln("%s %s", key, value);
        }
    }
    return 0;
}
-------------
compile:
dmd -c a.d
dmd -c b.d
gcc a.o b.o -lphobos2 -lpthread -lm

...and get errors:

If rewrite a.d as:

module a;

class A {
    private int[][int] n;

    public int[] foo() {
        return n.keys;
    }

    public int[][int] foo() {
        return n;
    }
}

It compiles fine.
