Stronger typing is desirable in complex performance oriented 
system level programming. This is the biggest weakness of C. 
Modules are clearly weaker than class/struct level protection. 
Weaker typing is not better in this context.

But «private(this)» is inconsistent and ugly. Other languages 
being ugly is not a good excuse. Most fields should be marked 
class private and that makes this uglieness a burden.
