What is wrong with this code? Running on ruby 1.8.6  
#==================================  
module MFoo  
def printme  
puts ‘MFooPrint’  
end  
def initialize  
puts ‘init’  
end  
end  
class Foo  
include MFoo  
def printme  
puts ‘FooPrint’  
end  
end  
class Foo2 \< Foo  
def printme  
super.printme  
end  
end

s = Foo2.new;  
s.printme  
#==================================

## This code outputs:

C:/Users/Volodymyr/Documents/NetBeansProjects/RubyApplication3/lib/  
main.rb:17:in `printme': undefined method`printme’ for nil:NilClass  
(NoMethodError)  
init  
FooPrint  
from C:/Users/Volodymyr/Documents/NetBeansProjects/  
RubyApplication3/lib/main.rb:22

in ruby super calls the ancestor method. No need to append .printme
