Subject: Re: Top level function definition gets in Kernel module?

Almost everything in ruby is an object.  All objects inherit from 
Object.  Kernel is a class, but Kernel itself is also an object, so it, 
like all objects, inherits from Object.  Therefore, all instance methods 
in Object are inherited by Kernel

Note the circularity: Object includes Kernel, so all the Kernel methods 
are instance methods of Object.  As noted above, Kernel inherits from 
Object, so Kernel actually inherits all its own instance methods.
