ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

therubygame deconstruct by @czetter

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.

Making it readable

matematikaadit's original submission:
