I edited because the code I looked at seemed to be atypical, comparing it to what others have posted. No, I don't think I'm M3 at all--though my father probably is, as he picked up programming in his twenties and knows many languages. As I had expected the code to look like nonsense, I was merely surprised I could get some idea about what was going on. My prior for being able to get a programming job with <300 hours of dedicated practice is low, but it could be something to investigate as a hobby.
