Us old folks remember the days when reformatting was a computationally expensive action that required a special program to “pretty print” the code. And heaven forbid your code used some language feature your pretty printer didn’t understand and mangled the output making your code uncompilable.
Well, I'm not that of a young folk. I was playing with computers (programming, in fact) in the early 90s, and I remember when it was expensive.
However, Eclipse is formatting C++ code with a simple hotkey and without breaking it and understanding the language for the last 15 years as far as I can remember. It's instant, too.
Because of that I feel a bit surprised when younger people look it like it's black magic. It's neither new, nor unsolved in my conscious experience.
