Dynamic in .Net - What is it really? with Joseph Swan

What is "dynamic" really good for? How does it work? Is it as fast as Microsoft claim and how did they manage this? There will be some code examples which show how they can be used in production code and also some fun uses of them that maybe have no real world use, but are a good way to understand how they can be leveraged. This will include an intro to ExpandoObject and also creating wrappers for data structures and even some playing about creating Ruby-style DSLs using dynamics. The pros and cons of each approach will be highlighted as it's not all unicorns and rainbows, but it's definitely a way to expand your tool belt of "fun things in C# to use that are actually useful".
