What if two classes in the module that are several meters apart
make `mistakes` that change the privite variable of `another
class`?
No one can guarantee that after `a few months`, even if you are
the author, you will not make mistakes, so as to misuse private
variable, while `class level` private can be completely avoided
it!
There is no maintainability, because two `out-of-class`
functions may quietly change your private `variables`.
In a module that contains a class, and other code as well
(perhaps other tightly coupled classes), you can know **nothing**
at all about that type (or any other class) without knowing
**everything** else in the module. If one understands this, then
one understands the problem here ;-)
.. btw. other code.. includes unitests as well.
The solution that D provides, is not a solution. It's a design
constraint being forced on programmers. Anyone that argues
otherwise, is speaking out of their ...
