Unfortunately, to achieve the functionality I described, I must have used reflection like that, which is not really nice, but I really prefer it to context based methods type assuming and casting which is essentially the same. I know people do not like reflection that is used like this, but the performance is not a concern, and I really got tired of transforming user input and checking for errors in each handler.
