[Haskell] Typeable and Data instances for Double, FiniteMap, ...

[Simon Peyton-Jones]

| Yes, once you start to use the SYB library you end up wanting it to
| cover almost all your types.
| I will make an effort *now* hoping that all the instance can still
make
| it into GHC 6,4.
| (There are indeed a few more unsupported types that make obviously
sense.)

Yes, anything in the HEAD will get into 6.4
