As an extension or alternative to this, what about a two value assigment
where the second value is assigned if the first value is false or nil:

files = { "item1" => "myfile.rb", "item2" => "mytestdata"}
window.caption = files[current_item] alternative "Untitled"
or
window.caption = files[current_item] \/ "Untitled"
