This is a deconstuction of matematikaadit's submission to therubygame challenge 5; 'Roman numerals. What are they good IV?'. The goal of the challenge is to take a string representing a roman numeral as input and return the integer that the numeral represents.
matematikaadit currently has the honour of the shortest (by character count) submission for this challenge. At first glance I didn't understand how it worked so I re-wrote and analyzed it until I did.
matematikaadit's original submission:

| #example usage: | |
| # instead of this - | |

| # class Message | |
| # attr_reader :content, :sender, :subject | |
| # attr_accessor :event | |
| # def initialize(message) |

| end_of_next_month = 1.month.from_now.end_of_month |
