I challenge you to write a more elegant re-interpretation of the following Ruby code in a different language:

module Factorial
refine Integer do
def ! = (1..self).reduce(:*)
end
end

using Factorial

puts 3.!

For a dozenal tally, three dots to line actually works better with a slightly lower average number of strokes. And you can use the Mayan numerals in Unicode:
1: 𝋡 2: 𝋢 3: 𝋣 4: 𝋥 5: 𝋦 6: 𝋧
7: 𝋨 8: 𝋪 9: 𝋫 10: 𝋬 11: 𝋭 12: 𝋯

What a ride it has been! I've cashed out... But mind that I'm 60, retired, and ready to spend some money. For those buying, good luck! $BCH has been outperforming $BTC lately and is looking good!

AOC is not dumb, but needs to be grounded in reality. The fallacy of a democratic power "fixin" socialism is now evident with our DEMOCRATICALLY ELECTED president Trump... No, democracy won't fix things.
