I have of course cited numerous papers on this, should anyone 
'actually' be interested in learning about it.

Anyone that uses abstract data types, should know, already, of 
the advantage of keeping that types representation 'private'.

I should not need to provide evidence for this. Do you know how 
silly that sounds?

'private(this)' in D, will finally provide the ability to do just 
that.

Of course, if you genuiely believe, that every abstact data type 
should go in it own module, then the is zero benefit from 
private(this).

Also, if you genuiely believe that programmers do not make 
mistakes, then there is zero benefit from private(this).

btw. The idea of private(this) does not take priority over more 
pressing issues in D.

That is a red-herring argument.

If it gets in, it's because someone chose to 'volunteer' their 
own time, to put it in.
