Subject: Doubt about rake and task

Hello,

I'm checking some implemented code and I've seen something like that:

----------------------- RAKEFIKE ---------------------------------

$:.unshift File.dirname(__FILE__)+"/rake"
require 'rake'
require 'rakeTest'

task :default => [:Where, RakeTasks.create ]
task :Where do
  puts "Welcome to the rakefile"
end

------------------- TESTFILE ------------------------------------


module RakeTasks

  def self.create
    puts "--Execute task1"
    Task1.create
    puts "--Execute task2"
    Task2.create
    task :end =>[:die]
  end

  module Task1
    def self.create
      puts "Hello World"
      task :die do
        puts "I want to die"
      end
    end
  end

  module Task2
    def self.create
      puts "I'm growing"
    end
  end

end
---------------------------------------------------------------

The output for that is:

c:\Programs\checkingRuby>rake
(in c:/Programs/checkingRuby)
--Execute task1
Hello World
--Execute task2
I'm growing
Welcome to the rakefile
I want to die

But with the same test file only modifying the Rakefile as follows:

----------------------- RAKEFIKE ---------------------------------

$:.unshift File.dirname(__FILE__)+"/rake"
require 'rake'
require 'rakeTest'

task :default => [:Where,RakeTasks.create,RakeTasks::Task1.create ]
task :Where do
  puts "Welcome to the rakefile"
end
-------------------------------------------------------------------

The output is:


c:\Programs\checkingRuby>rake
(in c:/Programs/checkingRuby)
--Execute task1
Hello World
--Execute task2
I'm growing
Hello World
Welcome to the rakefile
I want to die
I want to die


So, I don't understand how the calls are queued before being executed.
In both cases it starts with the classes task1 and task2 but the task
Where is executed always after the classes even though the call inside
the hash is declared before, same case is happening with the execution
of the task die although it is defined at the end of the hash.

Could anybody explain me how ruby is queuing or organizing the tasks or
just attach a reference to be reviewed? The only documentation I found
didn't take into account nested tasks execution.

Thanks a lot!
