How can I use a namespace in a Rake task dependency?
namespace :demolition do
  task :fire_bazooka do
    puts "kaboom!"
  end
end

# Single prerequisite
task :fire_bazooka => :load_bazooka do ....

# Multiple prerequisites
task :fire_bazooka => [:safety_check, :load_bazooka]

task :photograph_destruction => :demolition:fire_bazooka

namespace 'demolition' do
  task 'fire_bazooka' do
    puts "kaboom!"
  end
end

task 'photograph_destruction' => "demolition:fire_bazooka" do
  puts "snapping pics! yay!"
end

task :photograph_destruction => "demolition:fire_bazooka" do
  puts "snapping pics! yay!"
end

task :photograph_destruction => :'demolition:fire_bazooka' do
  puts "snapping pics! yay!"
end
