This is of course a personal opinion, but I think the interface of:
fileAccess :: FilePath -> Bool -> Bool -> Bool -> IO Bool
http://haskell.org/ghc/docs/latest/html/libraries/unix/System-Posix-Files.html#v
:fileAccess
is not very good.
The underlying system call access() is strongly disrecommended, so
it's not really worth a better interface.
I can't see problems with access function.
Of course it is a problem if used incorrectly:
if (access("foo", F_OK) {
fd = open("foo", ...)
}
The problem is there are very few uses of access() which are safe and
not already covered better by stat() (getFileStatus).
