Is it possible/desirable for the APR module to add a general purpose
vararg function called "pack" (symmetrical with the existing "unpack" in
the standard library) that collects all its arguments into a table? I
suspect it might be more difficult than this - there is probably a good
reason why there is no "pack" function already in the standard lib.

Anyway, if it is possible, you could just write:-

    local table = pack(apr.stat(path))

...for the first case.
