deriving Bits

[Kazu Yamamoto (=?iso-2022-jp?B?GyRCOzNLXE9CSScbKEI=?=)]

Hi,

Recently, I found that we can put Bits in "deriving". I checked the
GHC manual but it seems to me that this page does not cover Bits:

	https://www.haskell.org/ghc/docs/7.8.3/html/users_guide/deriving.html

Are there any other classes which can be automatically derived and are
not listed in this page?

If the number of such classes is not large, how about adding them to
this page?
