Subject: argh! more undocumented mysteries: to_yaml

Beginner woes, here, no doubt, but woes nevertheless.

I'm exploring the wonders of the Object class, and I see Object#to_yaml. 
Seems pretty obvious what to expect here, which would seem to account 
for the total lack of documentation in each of the gazillion instances 
of this method which appear in core library. Still, let's test it...

irb(main):010:0> [2,5,3,6,'abc'].to_yaml
NoMethodError: undefined method `to_yaml' for [2, 5, 3, 6, "abc"]:Array
        from (irb):10
        from :0

Can someone explain what just happened?

Thanks!

t.
