Is there a way to instantiate an object and have a string member take the object's name? I would also not mind for a gcc builtin.

Here's an example:

#include <string>
    
class A
{
    std::string obj_name_ = /* set to the objects name (very_descriptive_name) somehow */ ;
};
    
A very_descriptive_name; // naming the *object* should be enough, do we really have to initialize the string with exactly the same name?

The string is later used for recognisability.

    the name of a variable != name of an object. Consider that you can do A& a_completely_different_name = very_descriptive_name;, now the two refer to the same object via completely different names. You can do A a("very descriptive name"); Commented Apr 2, 2022 at 14:15
  • I'm not sure to understand your point. Couldn't you add a member function returning to string very_descriptive_name.str()? Commented Apr 2, 2022 at 14:17

  • @463035818_is_not_a_number: I know you can do that but that's an extra step. I want the member string to be infered from from the object name Commented Apr 2, 2022 at 15:08
  • @Bob_: I don't think you understand the point. I wanted to create an object which takes its object expression name and initializes a string member with it. Commented Apr 2, 2022 at 15:09
