SimpleSlot is the type of slot which underlies a var pattern. It has a value which can be replaced at any time.
The name is a legacy from when such slots were the unmarked case in Kernel-E (that is, the pattern "foo" created a SimpleSlot).
You can obtain a read-only facet on a SimpleSlot via Slot#readOnly/0.
