is this possibly a bug in dmd ?

[CODE FILE "test/inter.d"]
module test.inter;

interface IFoo {
    package void bar();
}

class Foo:IFoo {
    package void bar() {
    }
}

[CODE FILE "test/testMe.d"]
module test.testMe;

import test.inter;

class Test {
    IFoo    member;
    this() {
        member = new Foo();
    }
   
    void bla() {
        member.bar();
    }
}

[CODE FILE "main.d"]
module main;

import test.testMe;

void main(){
    Test test = new Test();

    test.bla();
}

Gives linker error:
test\testMe.obj(testMe)
 Error 42: Symbol Undefined _D4test5inter4IFoo3barMFZv

why is this?

Don't quote me on this but I think I heard that 'package' methods are oddly 
non-virtual.  Try removing the 'package' attribute from the interface/class 
methods.

'package' has never been given much attention, sadly.  The thing is that 
'package' is an entirely different animal from 'public', 'private', and 
'protected', but D doesn't seem to treat it as such.  'package' controls 
visibility between modules; it shouldn't have any effect on whether a method 
is virtual or nonvirtual.

(Yes, this has been discussed before, probably for at least two years, if 
not longer.  Nothing has ever been addressed.)

It is said that interface methods should all be public, since doing 
otherwise kinda goes against the purpose of an interface (which is to 
expose an inteface :P).
Try making the interface itself package, instead of the interface's methods.

Hum, I forgot: that's how it *should* work, but D currently doesn't 
honor protection attributes for types(classes, interfaces, etc.), only 
for variables and functions.
