Hi.

When I do
- ---------------------------------------------------------------------------
class Foo
~   def bar
~      puts "bar!"
~   end
end
- ---------------------------------------------------------------------------
and then
- ---------------------------------------------------------------------------
class Foo
~   def another_bar
~      puts "another bar!"
~   end
end
- ---------------------------------------------------------------------------
am I adding another_bar method to the Foo class instance or on it's metaclass?

I was reading

http://www.rubygarden.org/ruby?GavinSinclair/MetaClassDiscussion
"Ruby classes are themselves objects, being instances of the metaclass
~ Class. . . . The class Object is at the root of the hierarchy. . . .
~ Object itself is the only object without a superclass."

and then

http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/40537
where Matz says that
">I've been trying to understand metaclasses
You don't have to, because there's no such a thing in Ruby."

and

http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/40548
where Matz call them as meta-objects.

So, seems that there is some meta(class|object) around there (specially if
you think about the graph here
http://www.rubygarden.org/ruby?ClassInstanceVariables, where explain the
class methods), but I'm curious of when adding a new method as described
above, where it is added, on the metaclass or on the class instance, to
reflect the new method on all current and future instances of Foo.

Thanks!
