#The secret weapon in your refactoring toolbelt: Types

Types. Even saying the word makes most Rubyists run, screaming for their lives. Didn't we do away with all that public static void main nonsense a long time ago? Well yes. Yet: we shouldn't underestimate the importance of thinking about types. Even when building apps in ruby.

• How to use types to improve our applications
• What affects types have on our objects every day
