in C# 4.0: var, object and dynamic - Miguel de Icaza on Miguel de Icaza's blog
I don't really understand the need for a dynamic keyword. Of course, being able to handle dynamic languages in the framework is great, but C# is inherently a static language. No truly dynamic language need a dynamic keyword ;-) I think it will make things more complex and difficult to understand for programmers.

C# is slowly evolving into a multi-paradigm language. I say slowly because Anders does not like to add features to the language that he will later regret. He has historically chosen to keep features away from the language until all of its implications are understood.
The case for dynamic is pretty straightforward I think. Each side has benefits for productivity, and in a world where you must interoperate with other systems (the web, xml, rest services, json, untyped collections) adding dynamic support into the language means less frustration.
Additionally, every time someone needs to invoke something dynamically, there is a chance that he might introduce errors due to not covering all the possible use cases that might arise in real life. By having the compiler take over this job, hopefully there will be less bugs in this area.
