Conclusion

I hope you enjoyed this collection of tips. Of course, it is impossible to write about all the ways to write a program incorrectly, and there is probably no point in doing this. My aim was to warn a programmer, and to develop a sense of danger. Perhaps, next time when a programmer encounters something odd, he will remember my tips and won't haste. Sometimes several minutes of studying the documentation or writing simple/clear code can help to avoid a hidden error that would make the life of your colleagues and users miserable for several years.
