Fizzbuzz is a popular interview question for programmers (so I've read, I've never been asked it).

It goes like this:

Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". from Coding Horror

Not difficult. But why restrict the magic of FizzBuzz to an interview, throwing away perfectly working code you could be using in production?

Now you don't have to. FizzBuzzard monkey patches Fixnum so that all multiples of 3 display as "FIZZ", all multiples of 5 as "BUZZ", and all multiples of 3 and 5 as "FIZZBUZZ". All the way through your program, for absolutely every Fixnum.

Here's how to use it:

gem 'fizzbuzzard' # in your Gemfile

require 'fizzbuzzard'

puts 3  # => "FIZZ"
puts 5  # => "BUZZ"
puts 15 # => "FIZZBUZZ"

(1..100).each { |n| puts n } # solves FizzBuzz!!
