Do not use the err keyword. It was introduced in the 5.9.x development series, and made available to all the 5.8.x builds by patches (maintained by me).
The community however decided that err did not have enough good reasons to stay and was removed later on. That made me feel sad, but I am not the one that makes the final decision. The bottom line is that err, which was a special type of operator that could be overruled by a local function with the same name, is not available in 98% perl. Do not use it.
