From the FAQ:
I'm confused! What questions are on-topic for this site?
Simply ask yourself the following questions. To be on-topic the answer must be yes to all questions:
3. Is it actual code from a project rather than pseudo-code or example code?
So, I flagged this question, since it is clearly example code with no real purpose, with a message reading:
Off topic: "Is it actual code from a project rather than pseudo-code or example code?" OP is unresponsive to requests for further information in comments.
But my flag was declined with the boilerplate "no evidence" message.
What am I missing here?
Update: the OP has now responded to comments, confirming that it is example code.
