MATLAB: How to return the name (identifier) of the object from the call, inside a method of that class

class object-orientedoop

Here is a simple example:
classdef simpleClassA
      properties
          prop1
      end
      methods
          function obj = simpleClassA(x)
              obj.prop1 = x;
              objName = whatsMyName?
              fprintf('Property prop1 of %s = %g', objName, x)
          end
      end
   end
Then, at the command prompt, I construct an object of simpleClassA by:
Gold = simpleClassA(3.0);
and I expect this to display:
"Property prop1 of Gold = 3.0"
What function is "whatsMyName?" in my constructor method that would give me this result?
When I searched the MATLAB Answers database, the closest thing to what I want is these two links below but not exactly:
How can I return a char of object variable name from a method

You need the techniques described in https://www.mathworks.com/matlabcentral/answers/16693-within-a-function-get-complete-command-line-calling-text-a-la-dbstack to get the text of the executing command, and then parse it to find the variable name.
Keep in mind, though, that it is legal to have multiple statements on the same line:
   set(Gold, 'prop1', 3.0); set(Silver, 'prop1', 3.0);
You might find it difficult to figure out which of the two set() you are executing.
