Coders are slightly given to making snide remarks.
Not that this is always a fault; it is often solely for entertainment with no malice intended.
I rather enjoyed this warning, on Puphpet.com:
Attention: if you see some sections with non-sensical array keys (ex: rIreAN33ne2a) that means they have to be unique! If you copy/paste to add new settings, you must ensure you change this unique key to some other random string! Bad Things Will Happen if you don’t.
