These kinds of people are terrible coders. They are made aware of one possible thing that could go wrong in a piece of code they're writing, and once they avoid that trap, they magically think since they avoided that one pitfall, they are on top of their game, and then proceed complacently to write the rest of the code. Months later we find it is full of pitfalls which could have been avoided if they paid attention.
