In #19048, an iterator iterating over the cartesian product of two possibly infinite iterators is needed.
This can for instance be implemented by the Cantor pairing function https://en.wikipedia.org/wiki/Pairing_function#Cantor_pairing_function , i.e. the well-known proof that the product of two countable sets is countable. Does such an iterator exist in sage? I found the sage.misc.mrange module, but I do not have the impression that it deals with infinite iterators.
