well.. it didn't take long for the passive-aggresive types to 
come out of the woodwork...now did it.

my argument clearly lays out why I believe it is useful.

your argument is, 'it's not important to us - because you (me) 
are just the 0.1% , and we're the 99.9%'.

I don't find that a credible argument worth considering any 
further.

the argument that I have access to the source file is a strawman, 
and will not be considered any further.

The decision to friend or unfriend should be a design 
consideration, and not a design constraint enforced onto you by 
the language.

D has removed the need to use C++ like friend.

Now I need a suitable, enforcable, design constraint, so i can 
unfriend.

I don't know why Java always comes up??

I'm coming from C#.

In any case, C#, C++, Java, Swift..etc.. are arguably, one of the 
most widely used programming langauges in the world. The concept 
already exists across these languages. Millions of programmer 
already work with this concept (although apprarently it's not as 
clear cut in Java as one would expect).

What you're saying is, either these millions of programmers don't 
really need this feature, or they just don't need it in D. I 
cannot find the basis for either assertion in your response.

I'm pretty sure that's exactly what I've done.
