No. I'm saying that *if* isDirectory existed, then (isDirectory
"/no/such/directory/") should equal true on Unix. I'm saying
"isDirectory" should not *exist*, because it cannot do what it says on
Unix or Windows. There are OSes where it can do what it says (i.e., it
is possible to tell whether a path points at a directory or a file).
