this is just not true. don't put the damm class in module scope 
if you don't want it accessible.
It's just your unwillingness to adjust your programming to the 
language that causes these problems. The language offers enough 
tools to deal with it, you just don't accept them as valid, 
because you are used to _your perceived correct way of proper 
encapsulation_.

In reality the encapsulation boder is totally arbitrary. And you 
have failed to even give one _real world_ example of a bug it 
would have prevented.
In reality, noone is randomly accessing private state. It's a non 
issue in languages that don't have the feature.

And im most cases i'd argue that private(this) would actually 
enurage bad code design, so there is reason not to have it, like 
goto.

Anyway, feel free to write a linter, i'm sure there are other 
people who would apreciate it.
