Ooops! I am, as they say, an idiot.
Yesterday's tar ball is a wee bit lacking in essential files, as it were (the slight restructuring saw some functions being broken out into helpers.lisp and I wasn't packaging imports.lisp at all).
In further not-really-news, clast and Zaitcev have been discussing FizzBuzz (basically, count up from 1, for each n == 0 MOD 3, say Fizz, for each n == 0 MOD 5 sau Buzz and if both, FizzBuzz). Dividing by 3 and by 5 is, essentially, trivial in the decimal system. I first encountered this as a drinking game, with the addition that any 3 in the decimal expansion was also a Fizz and any 5 in the decimal expansion was a Buzz (and again if it's both a Fizz and a Buzz, it's a FizzBuzz).
This variety is slightly harder, in that you end up with 8 Fizz and 2 FizzBuzz between 29 and 40. Surprisingly hard, once you get into drinking game territory, around 2 AM.
