This is what its all about :-)


Another example where 'collect-join' could be useful


I have such pieces of code everywhere in my code in order to debug.
  def debug
    $log.puts "XXX "+data.join("\nXXX ")
  end   

But it duplicates "XXX ".. not nice.
I could do like this, but I think its unnecessary complicated
  def debug
    $log.puts data.collect {|d| "XXX #{d}\n"}.join
  end   


It could be written really nice using 'collect-join'
  def debug
    $log.puts data.join {|d| "XXX #{d}\n"}
  end
