In principle, given a domain with k elements and a rule with n variables, there
should be exactly k^n many labeled variants of that rule.
The proof looks as if n would be chosen globally
as the maximal number of variables in some rule.
Yes, that is what is happening at the moment.
Since CO4 has caching/hash consing throughout,
it hopefully will not waste space - but time (for the cache lookups).
