title: C# 4: Real-World Example of Dynamic Types
body: <p>I think I have my brain halfway wrapped around the Dynamic Types concept in C# 4, but can't for the life of me figure out a scenario where I'd actually want to use it.</p>
  
  <p>I'm sure there are many, but I'm just having trouble making the connection as to how I could engineer a solution that is better solved with dynamics as opposed to interfaces, dependency injection, etc.</p>
  
  <p>So, what's a real-world application scenario where dynamic type usage is appropriate?</p>
