OK...now THIS is the reaction I was really looking for, which is why I 
provided the documentation I did in my first two emails. From my point 
of view, and as your response here would seem to support, beginners like 
me can, in exploring the interface to Ruby (part of which is its 
available documentation) find glitches which those of you with expert 
knowledge all too easily miss. We are, in fact, a uniquely valuable 
resource, I would hope. I'm trying to be, in any case.

So...here's the path to the documentation (can't give an specific URL, 
due to use of frames):
1. go to http://www.ruby-doc.org/core/
2. in the middle panel, select the Object class.
3. scroll down to Methods, and find the to_yaml method
4. clicking on that, you'll see there's no documentation. So, go back to 
the top of the Object's page, and see the sentence I noted in my second 
email: "  Object is the parent class of all classes in Ruby. Its methods 
are therefore available to all objects unless explicitly overridden."

To my mind, there is nothing here that suggests that I must "require" 
anything to get access to this method. Hence my (enduring) bewilderment. 
Were I more knowledgeable about object inspection, I'd have seen why I 
got the irb error I did, but still would not have know why irb blocks 
this method.

I hope this helps the cause, and thanks for your interest.
