Where is instance_eval() defined?

Where in the hell is instance_eval() defined? In "The Ruby Programming
Language", it says it's defined in Object, but the 1.9.2 docs don't list
it in Object:

http://www.ruby-doc.org/core/classes/Object.html

Nor is it listed in BasicObjec, Kernel, Module, or Class:

http://www.ruby-doc.org/core-1.9/classes/BasicObject.html
http://www.ruby-doc.org/core/classes/Kernel.html
http://ruby-doc.org/core/classes/Module.html
http://www.ruby-doc.org/core/classes/Class.html

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.

Nor is it listed in BasicObjec

p RUBY_VERSION # => "1.9.2"
p BasicObject.public_instance_methods.grep(/eval/) # => [:instance_eval]

and in vm_eval.c:

rb_define_method(rb_cBasicObject, "instance_eval", rb_obj_instance_eval,
-1);

Thanks. Does anyone want to fix that in the 1.9.2 docs?

Also, I can never find the methods() method anywhere. Module?
BasicObject?

In future do this:

    method(:instance_eval).owner #=> BasicObject
