Comment:
I also did some cleanup:
- I removed the caching of the elements since the e/f operations aren't
cached (which I think is where the real speed gains are) and it was a hack
of a cache.
- I removed the `list` command because that (and the respective caching)
is done by `FiniteEnumeratedSets` (and will result in a speedup for
iteration after calling `.list()` once).
