Subject: Fixnums can have instance variables?  Cool.

This really surprises me:

3.instance_variable_set("@unbelievable", "believe it!")

puts 3.instance_variable_get("@unbelievable")		# -> "believe it!"

which led me to:

class Fixnum
   attr_accessor :note
end

13.note = "a baker's dozen"
25.note = "5 squared"

notes = [13, 21, 25].collect { |x| x.note }		# ["a baker's dozen",  
nil, "5 squared"]

Am I the only person with their jaw on the ground?
