It's an action!, not a native!, that's why native? returns false. But, the point is that it is an internal action, that is not supposed to be used by users. It was being unset in older rebols but it is not in newer versions. It should be safe to unset it.

I'm not, but I can guess. I've seen some bits of C code so I know that the docstrings are embedded in C comments; I guess Carl has a script that extracts them and builds the rebol code that "defines" the natives (see the other "mysterious" function called "native"). So since the whole process is automatic, PATH is there even if it should not. :) Regards, Gabriele.
