How to find out object type

umm, perhaps I am doing something wrong:

irb(main):005:0> o.kind_of(0)
NoMethodError: undefined method `kind_of' for 123:Fixnum
        from (irb):5
irb(main):006:0> o.kind_of(1)
NoMethodError: undefined method `kind_of' for 123:Fixnum
        from (irb):6
irb(main):007:0>

object.kind_of?( Array ) #=> To test if it is something
object.is_a?( Array ) #=> Same

object.class #=> Tells you what class the object thinks it is.

methods may have punctuation in ruby. kind_of?( OBJECT ) uses a question
mark.

It makes it into a question. Effectively what happens as I understand it is
you ask the object what kind of object are you?

eg

o.kind_of?( Fixnum )
