You may or may not be excited about C# getting extension methods but this idea is a core part of Ruby. IronRuby carries this spirit into .NET where it's a simple matter to add a method to an existing class--even a BCL class. As rich as the BCL classes are, there are times where a bit of functionality is just plain missing. In sticking with true object-oriented practices, Ruby makes it easy to add that functionality where it belongs.
