> Most importantly, though, this sort of debugging is performed using the same language and user interface I use all day to write code in the first place, so I don't have to spend time trying to remember how to do stuff in a debugger... it's just code. Absolutely! Running a commandline debugger adds additional context I have to keep in my head (syntax for all the commands, output format etc), that actively competes with context required to debug my code. Printfs work just fine without incurring that penalty, granted this argument applies less to IDE debuggers because their UX is usually intuitive.
