`_cmp_` etc. But it might be a personal feeling.
Ok, then let's keep them as they are.
> > 3. should `list(cache)` appear in the code so that the cache cannot be
changed 8accidentally) from outside since only a reference of the list is
passed? This would also allow e.g. tuples as well. Or is it meant that
`cache` really specifies the cache itself and not only the cached
elements. If so, can we make this clear in the doc somewhere (description
of `lazy_list`)?

`__init__` method we clearly want to use the reference to the same list (I
made it clear in the doc). In the factory `lazy_list` I am in favour of
copying and adapted the code accordingly.
Good solution.
