Thanks for the response Ethan I think that I will leave the tests as they are in the current patch.

> No doubt, there are exceptions to the rule in the standard library which is less consistent than we might like:  "stat_result".  That said, stat_result is a structseq and many C type names are old or violate the rules (list vs List, etc).   New named tuples should follow PEP 8 can use CapWords convention unless there is a strong reason not to in a particular case.

I actually thought we should keep on consistency with other "result" like objects. I can see your point about new named tuples that should follow PEP 8 and DirEntry is an example of new "result" class that follow PEP8.
What names do you suggest? Maybe DirInfo and FDirInfo?
