You made a very good guess ;)

    puts x.type # prints "Fixnum"
    puts y.type # prints "Array"
    puts z.type # prints "Hash"

Note that for Ruby 1.8, the type() method is deprecated and you should 
use class() instead, i.e.

    puts x.class # prints "Fixnum"
    puts y.class # prints "Array"
    puts z.class # prints "Hash"

Hope this helps,
