dynamic: Case Study with IronPython
All powerful tools should be used with care, and
dynamic is no different. By no means is
dynamic meant to be a substitute for static typing. Use of static typing provides many benefits, such as compile-time checking, tooling advantages, a more beneficial performance profile, and so on.
The main philosophy of .NET 4 dynamic is to make reaching out to dynamically typed code and data simpler. Or to say it in another way: Why should someone be punished for embracing some piece of dynamically typed code (for example, using some Python-based library), when calling it from languages like C#? In short, C# 4.0
dynamic allows developers to “ease into” the domain of dynamic typing with minimum friction.
