I always get surprised in the opposite direction by languages that work like that, fun to see it from the other side. As for the second mistake listed, this is practically the reverse confusion itself... I remember one time in an interview, I got this bit of arcana about Go slices right and the interviewer insisted it was wrong, and despite the evidence being on the screen in the program output at the time, I just backed down. Not sure why I or anyone ever submits to the indignity of job interviews, but it also soured me on Go itself a bit!
