Thanks for that. I am arranging to take 2 parameters...

users = User.find(:all)
  users.each {|namex, user| nameb.call(namex.name) 
borrowed.call(user.books_borrowed) }

I get the following error....

 books.rb:80: syntax error, unexpected ',', expecting '}'users.each 
{|namex,user| (nameb.call(namex.name)), 
(borrowed.call(user.books_borrowed)) }


ps Thanks Phillip Gawlowski for that detail :)
