Structure for rake files

Is this possible to view structure for *.rake files with rake tasks definition?
Example.

Code
namespace :my_tasks do
  desc "Description of my task"
  task :my_task_name do
    # my task content
  end

  desc "My another task"
  task :second_task do
    # content
  end
end

Will be viewed in structure view as:
my_tasks
|
`- task
`- second_task
