This doesn't seem specific or particularly enabled by dynamic types? I don't really understand it yet and have barely used it but this seems like it's supported by expression trees / Roslyn / code gen stuff in .NET/C#? Is there a difference I'm missing here, e.g. writing some lambda and having the code generate code to run it against NoSQL or SQL or some other storage at runtime which is what I think things like LINQ2SQL do under the hood is basically equivalent right? This type of programming seems like it can be supported by both types of types?
