Because we were a 4-person company at the time starting to hire first employees and I realized I can't trust new people as much, so most certainly you cannot anymore do things like input_array[0] and committing to master because i took measures immediately after it happened, so that is not a problem. The problem is that the person(s) for whom I had to add these baby bumpers not to do input_array[0] will - and has - screwed up much bigger on everything that is slightly more complicated than that, too. Because if you are an engineer and you don't care, then no amount of padding around you will make you curious, careful, detail-oriented, non-lazy and capable of tackling hard problems that life throws at you every day at a tiny startup.
