I think it's a good idea. There's no real sense in maintaining two
different modules when the purpose of both is the same.

I vote for the iterator approach to directory traversing, because
it's lightweight (i.e: no need to create a big table with a lot of
strings, only a string at a time is generated) and if the iterator
is well written it could be used with Lua's generic 'for'. Something
like:

  for filename in fs.listdir('/some/path/') do
    -- do something with each filename
  end

I agree.

I think we could do something like the 'sys' module in Python: on 
Unix-like systems it uses the 'posix' module as backend, but when
running in Win32, it uses a windows-only module as backend. This 
approach is extensible, and some other backends could be added for
"exotic" operating systems with "funny" filepaths (I', thinking 
about VMS or RiscOS, for example :P)
