This operation is 'idempotent' in the sense that if cache_keys contains a single key
then that key is returned.
Note that this operation is commutative but not associative. We use the term 'combine' rather
than 'merge' or 'union' to remind the user of this. Associativity is not a necessary property,
in practice.
