My badly interpreted PL/SQL example was on the same page you point to

There is a private 'number_hired' which given its name I thought was 
counting the number of employee, but it was just counting the number of 
"hire_employee" calls in the current session... Not very interesting.

Indeed, I misinterpreted the Oracle documentation example.

I'm not sure I understand.

If you do not grant/revoke permissions as you want on the functions, then 
it can be invoked by anybody.

My point is that it is *possible* to tune permissions so as to control 
exactly who may access a private session variable.

That is exactly the same with a grantable session variable if you do not 
have done the necessary grant/revoke, there is no difference?
