G'day tobyink, Your usage seems to align with mine. For single loops, I don't generally supply a label. For nested loops, I'll generally give all loops a label; although, if I'm not using next, last, etc. I'll probably omit the labels, e.g. for processing all cells in a grid:
Not really related to loops but years ago, when working with junior programmers who didn't fully understand lexically scoped pragmata, I'd use labels to document anonymous blocks; usually something overt, such as:
This followed several instances where braces delimiting anonymous blocks had been removed because "they looked like superfluous code". — Ken
