Exception Driven Development

This is Hello World, run by exception.

In other words, it throws exceptions around in order to invoke methods. I know, it's exceptionally crazy.

How to

To invoke a method, throw a MethodInvocation, containing the target class, method and (optional) parameters, e.g.:

throw new MethodInvocation("ExceptionDriven.ConsoleApp.Worker", "Greet");

If you'd like to use an instance as the target class, then supply that one:

throw new MethodInvocation(this, "SayHello", name);

Don't expect the called method to return to the location you threw it from. That's not how Exception Driven Development rolls.
