This is highly amusing to me because my solution was almost exactly identical (and the same number of keystrokes:

  print(($_%3?"":"Fizz").($_%5?"":"Buzz")or$_,"\n")for 1..100

sadly, though it says they're running perl 5.14, it wouldn't work with 'say' which would have shaved off 7 characters.

edit: Guess what? The code above does not work. It's what I typed into my buffer, and then fixed it on the console to use || instead of or. Oh operator precedence!
