So I can append False to True to get False (Boolean monoid under &&) or append 8 to 9 to get 72 (integer monoid under multiplication)? There's also a monoid instances for any single-argument function into a monoidal type, where (f <> g) x = f x <> g x; I don't know what to call that but it's definitely not appending.
Append is a name that works in a few cases but horribly breaks down in the general case.
