Yes, this is exactly what will happen if one doesn't rely on
libraries. Everyone will handroll their versions of the same
thing. Just looking at that it is easy to say "nice code,
I know all these functions, that code is easy to maintain" but
actually all those versions aren't quite the same, and they
will start to drift even more afar. Some dude will think, "oh,
I understand this from somewhere else already" but it isn't
exactly the same, just something close to what he previously
saw. Replace all those with one library function - yes,
everyone will have to learn that function but it will be much
better code and also easier to maintain since it is much more
reliable, a neat module that always does what it does.
