Try this in the IRB console.
>> testhash = { :key1 => 'val1', :key2 => 'val2', :key3 => 'val3' }
>> testhash.each { | key, value | p key.to_s }
>> testhash.each { | key | p key.to_s }

My expectation was for the output to be the same in both cases.
Why the difference?
Why are the key and value concatenated?

Working with RubyMotion, I find myself repeating some tasks.  In an attempt to develop (for myself) some standards and scripts to simplify the repetitive tasks, I decided to leverage RUBY syntax.

Here is my "template" for the Rakefile I use in RubyMotion
============
  $:.unshift("/Library/RubyMotion/lib")
  require 'motion/project'

  Motion::Project::App.setup do |app|
    # Use `rake config' to see complete project settings.
    app.name = 'killerApp'

# A generic class to encapsulate the simple UIAlertView capability in iOS
# usage:
#           @alert = Alert.new { :title => "IMPORTANT ALERT", :message => "It is bad luck to be superstitious!"}
#           @alert.show

class Alert

  attr_reader :dialog, :alert_message, :alert_title, :alert_acknowledge

  def initialize(params = {})

class UILabel_Adjustable
	# Borrowed and modified the excellent example at http://www.11pixel.com/blog/28/resize-multi-line-text-to-fit-uilabel-on-iphone/
	# adapting it for RubyMotion
	#      This applies only to a multi-line label.  You can use '.adjustsFontSizeToFitWidth = true' for a single-line label

	# usage is:
	#   text = "It's bad luck to be superstitious"
	#   text_label = UILabel.alloc.initWithFrame([[20, 20], [70, 120]])
	#   text_label.numberOfLines = 0 # set 0 for word wrap
        #   text_label.lineBreakMode = UILineBreakModeWordWrap

# -*- coding: utf-8 -*-

# custom rake tasks
require '../raketasks/gemerator.rb'

desc "Open latest crash log"
task :log do
  app = Motion::Project::App.config

When I first uncovered Collatz conjecture it made perfect sense to me. You are simply dividing an even number in half until you reach one and, if the number is not even you coerce it to be so.

This created a flash of inspiration for me to devise this simple routine.

{This could be used as the basis of a program to prove the "unsolved problem" of whether Collatz conjecture applies to ALL numbers greater than one.}
