'Float' is a class, ins't it? So how can you do "Float(whatever)" as if 
it were a method?

Now, when I do "Kernel.methods" I _do_ see "Float", "Integer" etc in the 
list. Is it the method "Kernel.Float" that eventually gets called? How 
does ruby know to distinguish between the class Float and the method 
Kernel.Float?

BTW, why, when I do "Object.methods" don't I see "Float", "Integer" etc 
in the list? Some more methods too are missing. Object is supposed to 
inherit them from Kernel, doesn't it?
