You assume you get the error message when the method is defined. This is not 
true. The error is raised when the method is actually called (with a file 
object as a parameter). At this point ruby already knows that file is a File 
object (because that's what was passed into the method) - that's not the 
problem. The problem is that File objects don't have an eof method. It's eof? 
(with a question mark).
