    I'm surprised no one's suggested the obvious:


namespace.reverse_each do |i|
    # Do something with i
end


    ...this assumes you don't actually need an index, which is usually the 
case.  It also assumes that namespaceEnd is the end of a container called 
"namespace," or some such...

    If you need the index, instead of the array, you'll have to do something 
wild and zany, like:


namespace.reverse.each_index do |i|
    # Do something with i
end


    ...does this help?
