Comment (by ncohen):
Hello !
Could you add an example when the 'lattice' is given as a `Lattice`
object? Logically, it could even be the first kind of examples you give,
and you could then add that "it also works when 'other' is any iterable'".
Also, it seems that the code does not work as expected when 'other'
contains points which are not in `self`. That's a trivial 'no', but it
should not be an exception.
