Looks like yet another case in which I disagree with PBP. IMHO, only
the loops that need to be labeled should be labeled. To me a label is
a warning sign, something that says "hey, be careful here, this is a
place to which we might jump, a loop out of which we might jump while
inside another loop or something like that." I can't think of a good
similitude, maybe I could compare it to overabundance of trafic
signs. If you put up too many, the drivers will become distracted and
are more likely to ignore or miss the one that was really im****tant.
In either case "would probably be better to" doesn't look like
criticizing to me :-)
