How do you print the value for "a" and "i"?

thufir@arrakis:~/ruby$ 
thufir@arrakis:~/ruby$ ruby inject_one_element.rb 
result=2
thufir@arrakis:~/ruby$ 
thufir@arrakis:~/ruby$ cat inject_one_element.rb 
result = [2].inject do |a, i|
  puts "a:#{a}"
  puts "i:#{i}"
  puts "hello"
  puts "--------"
end



puts "result=#{result}"
if result.nil?
  puts 'yes'
end
thufir@arrakis:~/ruby$ 



thanks,
