Security issues even. If you want to write predictable code - you have to init your variables/arrays. And check for existence/null. If fixed at least a few dozen bugs in my system I took over in the last few months specifically because of undefined variables or indexes. It works for small stuff, but when you have a codebase with 100+k LOC and more, you have to go strict or it starts to cost a lot of money and personnel to keep things running along. -- Arvīds Godjuks +371 26 851 664 [email protected] Skype: psihius Telegram: @psihius https://t.me/psihius
