I'm curious: do you genuinely find that beautiful?To me all the enumerable/map/frozen string literal stuff seems pointlessly overcomplicated compared to the simplicity of just writing down what you're supposed to do:

  (1..100).each do |n|
    a = String.new
    a << "Fizz" if n%3 == 0
    a << "Buzz" if n%5 == 0
    a << n.to_s if a.empty?
    puts a
  end

(Disclaimer: not my code, on mobile so I stole that off GitHub)
