Re: Alan’s shape query: years ago I saw a documentary about the marketing campaign for Yorkie, during which they announced that it belonged to (as I heard it) the “cantiline bar” category. Googling now I can only find this engineering/shipping term as a possible non-chocospecific meaning (relating to the stacking of cylinders) for a reasonably similar word. Which would make the KKK a “cantiline” or “cantline square”? (Also of interest, from same documentary: rejected names for “Yorkie” = “O’Brien” and “Quinn”)
