This turns out not to be all that useful:

A.hx:
--------------
class A {
	private var aApi:AApi;

	private function new (aApi:AApi) {
		this.aApi = aApi;
	}

	public function foo () {
		aApi.bar(); // cannot access to private field bar
	}
}

typedef AApi = {
	private function bar ():Void;
}
---------
B.hx:
---------
class B extends A {
	public function new () {
		super(this);
	}

	private function bar ():Void {
		trace("bar");
	}
}
--------
Main.hx:
--------
class Main {
	public static main ():Void {
		var b:B = new B();
		b.foo();
	}
}
--------

A.hx fails to compile, since access to the private function in the
typedef doesn't seem to be allowed, even from the same file. This
looks like a bug?

Thanks,
Dan
