Hello! In `directory` package, there is a function `System.Directory.listDirectory`. It says on the box that it throws error messages that can be branched on. (`isDoesNotExistError`, `InappropriateType` and so on.) I dug into it a little, and it appears to me that, in actuality, on Windows (unlike on a Posix compliant operating system) there is no reliable way to sort the errors in some pre-defined categories like "no such file", "not a directory", et cetera. Therefore I must presume that either the documentation is incomplete and misleading, or it is I who is somehow misled. The information I have is summarized in a Stack Overflow question linked below. I would like to receive a clarification. Perhaps an amendment to the documentation should be considered? The point that initially aroused my suspicion is that `NoSuchThing` is associated with both `eNoEnt` and `eNotDir`. Is there a rationale behind this? From the `man 3 opendir`, I do not see the need for this ambiguity. This is the S.O. question I mentioned: stackoverflow.com/q/49212400 There is also a linked question that elaborates on the motivation behind my inquiry. Thank you!
