Without a suffix it looks equivalent to me. Why do you think they aren't 
equivalent?

That's the current File.basename behavior, isn't it?

File.basename("Not a Path") # => "Not a Path"

We have to decide whether or not the basename of a root path is itself

"\\.\" and "\\?\". I'm not sure if that topic has been revisited since then.
