I can’t figure out the correct syntax in a Rakefile to say that a  
certain task depends on a task in a different namespace. What is it?

If my question isn’t clear, please let me know. Is there no way to do  
this?

task :ci =\> [:rcov\_params, namespace(:test)[:rcov] ]  
doesn’t work

$ cat Rakefile  
namespace :foo do  
namespace :bar do  
desc “nested baz”  
task :baz do  
puts “foo:bar:baz”  
end  
end

desc “outer baz”  
task :bar =\> “foo:bar:baz” do  
puts “foo:bar”  
end  
end  
$ rake -T  
(in /home/batsman/mess/2006/46)  
rake foo:bar # outer baz  
rake foo:bar:baz # nested baz  
$ rake foo:bar  
(in /home/batsman/mess/2006/46)  
foo:bar:baz  
foo:bar
