I have read this article and it leaves me rather more confused than not.
I gather that I am missing something fundamental. Consider that when I
write x.to_s I am telling the object what to give back. But then what
am I doing when I write x.exists? or x.is_a?(y) or
Is this a semantic confusion on my part? Should I consider that what I
do with x.exists? is tell the object to answer a question?
