Hmm, in my (limited(*)) experience most industrial IT departments 
have coding guidlines that insist you use this-> in front of 
every class member/method to make it obvious that its a class 
thing and not a local function name. 

eg:

class foo{
private: 
	int x,y;
public:
 doit(int p)
 { 
   int z = 0;
   z = p + this->y;
   return this->x/this->y;
 }
};

So using self is only a minor hiccup.
use of unreferenced members is one of the most confusing
features of C++ programs to a maintenance progammer, and 
a bigger source of frustration that anything else when 
dealing with deep class heirarchies!
