Re: argh! more undocumented mysteries: to_yaml

[Note: parts of this message were removed to make it a legal post.]

I'm beginner to but I understand it. You cannot use to_yaml for Array,
because there's no method to_yaml for Array. Try to read about
Object#to_yaml in Ruby Documentation.

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!
