Ada is not C/C++, if the assignment operator is available in a type  
interface, that means it is safe to use. When the assignment operator  
would not be safe to use and/or would cost too much to the implementation  
to be made available safely, then Ada has well know way to exclude it from  
the interface: “limited type”.

So, yes, if “:=” is available in the interface, that means it's not a hack  
to use it.
