Re: [Haskell-cafe] Monoid wants a (++) equivalent

I'm sure there's some important historical reason... but why isn't '&' used in something more prominent than the fgl package? I understand why it's not used for bitwise AND in Data.Bits (I assume because the corresponding bitwise '|' operator isn't available), but all the other single-character operators** (in the ASCII range) are used in some core library (if not the Prelude itself). But not '&'. Why? It makes sense (to me) as a Monoid 'append'.

(?) is also undefined in Prelude.
