upper/lower/order-connected set (with the notable exception of the closure of an order-connected
set).

## Notes
## Implementation notes

The lemmas don't mention additive/multiplicative operations. As a result, we decide to prime the
multiplicative lemma names to indicate that there is probably a common generalisation to each pair
of additive/multiplicative lemma.
The same lemmas are true in the additive/multiplicative worlds. To avoid code duplication, we
provide `HasUpperLowerClosure`, an ad hoc axiomatisation of the properties we need.
