Amusing at this is, hard to believe that people are spending this much time
on an April Fool's posting.
I'm looking forward to similar postings on checkers and go pieces. As a
matter of fact, one that proposes adding new characters for every possible
configuration of a go board would be imaginative.
And I'm looking also forward to the ♖+ZWJ+⬛️ (etc) proposal.
