Now, that i see this type of programming, i could think to stay a couple of years more with This type of examples helps to contruct Object Oriented clases, same as Java (familiared with).

I could see a scenario were this type of declaration , would help you to define a runtime type of variable, and prevent exceptions, threads that will conduct to a system crash.

Now the other things that boders me is that, vb wont be around, cause we all know that csharp it´s a better language.

Do you see this as an alternative?
