I've been using Perl heavily for many years and have never once had the need to use a LABEL in production code. Granted, it has always been nice to know I could if I needed it. But I would never use a LABEL on a non-nested loop block, it serves no semantic purpose and does not help "self-document" a block of code. If you think otherwise then you have to ask yourself why you don't label or name every block of your code?
