NO, because this will lead again to non-upgradability hell. other libraries will need to import these types from different places depending on GHC version where they are runned

Ok, so how about a new module in base for Windows API error handling? E.g. a Foreign.C.Error.Win32 module which resembles Foreign.C.Error.

it will raise the same problem. imho, it's better to redefine as much as possible in other libs, or just reexport `base` types/functions via additional libs -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
