RE: ghci and unboxed ints

Fixed now!  Thanks for pointing it out.  The story is that you can only
bind lifted (boxed) things.

| I don't know what the issue is, but it is interesting:
| 
|         Prelude> :m GHC.Base
|         Prelude GHC.Base> case 1# +# 2# of a -> show (I# a)
|         "3"
|         Prelude GHC.Base> let a = 1# +# 2#
|         Prelude GHC.Base> show (I# a)
|         "1085417808"
