Hi Eric,

probably not very relevant (both extensions far above the quorum) but
it seems odd to include

> EmptyDataDecls: yes

but then say 

> EmptyDataDeriving: no

Als note that the docs at
say “The EmptyDataDeriving flag is only required to enable deriving of
these four “standard” type classes (which are mentioned in the Haskell
Report). Other extensions to the deriving mechanism, which are
explained below in greater detail, do not require EmptyDataDeriving to
be used in conjunction with empty data types.”

So enabling the other DerivingFoo extensions without EmptyDataDeriving
is somewhat non-uniform.
