Datatypes that can be made into sets must have a defined order. And since
set(address) is a valid data type, what is the ordering of addresses?
If you make an instance of type
set(address), how are the addresses ordered?

address data type is ordered lexicographically, so that
tz2... comes before
tz2a... comes before
tz2b... etc. But originated accounts, addresses that start with
KT1, come after any implicit accounts, those that start with
tz. So all addresses starting with
KT1 are ordered lexicographically but they come after all
This ordering is described here.
