The other way to do it is of course have a function that takes a 
pathname and returns a polymorphic object representing either a 
directory or a file.  It could then support the visitor pattern to 
enable you to easily write code that treated files and directories 
differently.  I'm not necessarily suggesting this is better, but 
should be considered.
