OK as is. Room for improvement.

I don’t think we need the variable at all. It’s also strange to use UNUSED_PARAM for this. The word is “delete”, not “kill”.

Also, I think we should have a helper member function to hide the use of "new". I don’t like having these calls to new with the comments in three different places in the file. It should just be one small inline function.

Ditto.

Ditto.

Since this is in the class definition, the inline keyword is unneeded.

Since this is only used in the .cpp file, it need not be in the class definition. I can be in the .cpp file, and just be declared in the class definition.
