Understanding Programming Errors Through Language

Code correctness is just the beginning, there is much more to it.

It was not bad, per se, but naïve, it missed the big picture, it didn’t anticipate problems. After a while, programming is not just about solving the current issues but avoiding future ones. And by that, I don’t only mean bugs, but also maintenance. For…
