How does one call from inside a namespace, a task from another namespace?

namespace :foo do  
&nbsp;&nbsp;&nbsp;task :a do  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;puts "Hello from task a!"  
&nbsp;&nbsp;&nbsp;end  
end

namespace :bar do  
&nbsp;&nbsp;&nbsp;task :b do  
&nbsp;&nbsp;Rake::Task[:foo][:a] # How to call foo:a ???  
&nbsp;&nbsp;&nbsp;end  
end

Thanks!

Rake::Task['foo:a'].invoke

#invoke will only run a task once. If you want to force it to run (minus any prerequisites) call #execute.
