Hi,
Linker fails to process following code when interface methods are private:
The same code with protected/public methods works fine...
-----------------------------
import std.stdio;

interface Foo {
  private void foo();

    public final void doFooFoo() {
        foo();
        foo();
    };

};

class MyFoo : Foo {
  override private void foo() {
        writeln("foo()");
    }
};

void main(string[] args) {
    MyFoo mf = new MyFoo;
    mf.doFooFoo();
    writeln("Done.");
}
---------------------------
Undefined symbols for architecture i386:
  "_D4stat3Foo3fooMFZv", referenced from:
      _D4stat3Foo8doFooFooMFZv in stat.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
--- errorlevel 1

Best Regards,
Blazej

private methods are implicitly final.  It is correct that it fails to link, but it should be an error as MyFoo.foo does not override any function.

Hi,
I'm not sure if all private methods should be implicitly final.
I've been trying to implement NVI (Non-Virtual Interface) Idiom found in
Alexandrescu's book (p213).
Could you please make sure about that?
Thank you,
Blazej
