imho, it would be a good thing for a future 'file system handling module'
to build more of an abstracted tree-like graph that may or may not be  
mappable
(and may or may not be used in a particular case to actually map)
to existing objects on a particular system. for example, i find it
a bit in my way a lot of times that all the locators i have os.path
handle for me are written according to the os, not in a unified,
abstracted way. given that there are a number of applications (xml
documents, file system handling, urls, archives...) that have very similar
requirements, maybe there is a useful abstraction that covers these
and other cases. some nitty-gritty details could be captured by suitable
specializations of the general case.
