Its USP is that efficiency has not been sacrificed. Internally, the library also uses Expression tree lambdas. .NET 4.0: 1. <http://geekswithblogs.net/sdorman/archive/2008/11/16/c-4.0-dynamic- programming.aspx> - C# 4.0 introduces the "dynamic" keyword which allows method calls to be resolved at runtime, rather than blocked by the compiler. This provides another (cleaner) solution to the problem.
