In fact, some participants in the mailing list discussion proposed adding non-alphanumeric characters to future release names just to see what happens. Paul Flo Williams predicted someone proposing "Motörhead's Moshpit" as the Fedora 20 release name because of the non-ASCII characters, while Richard M.
