this sends alarm bells ringing to me.  i would expect, from that  
small sample of code, that i could do

   a_ok = apps.all?{|app| app.info.root.exist?}

which is to say apps is a method or collection, an app knows it's  
info, an info object knows it's root, and that root is a Pathname  
object so therefore has an exist method.  which would obviate the  
need for a method ;-)
