Ah, APIs always involve these interesting decisions!  Both have their
benefits, and it's always possible to write variants that support both
'internal' and 'external' iterator styles.

Right - so the idea is to minimize subprocess creation as much as
possible. With the luafilesystem/luaposix dir iterators that file
search can be done, but copying files is somewhat tricky.  (At least
in Penlight I just use 'cp' on POSIX because otherwise I'd need
luaposix to sort out the permissions etc; on Windows, there's a copy
file function which I use.)
