D could add an new attribute to class members:  @deny

A @deny attribute can come before a classes private member, to 
indicate that the private member is to remain private, even 
within the module.

Cause sure, it nice to be among friends, but you don't want your 
friends knowing every thought that is going through your mind! 
Sometimes, somethings, just need to remain private.

@deny private string _userName;

now... _userName is no longer accessible at the module level, and 
class encapsulation is restored.

If had I any clue about compilers, I'd think this through more ;-)
