The following works in ghc-5.02:
ghci
...
Prelude> let {g:: Integer->Integer; g 0 = 0; g n = n+(g $ pred n)}
Prelude> g 0
0
Prelude> g 3
6
But Prelude> let {type T = Int; n = 1 :: T}
does not.
I wonder, whether there is any good reason for such distinction.
I would like too Haskell to behave like a good interpreter, with
self-applicability, dynamic features, like, maybe, some Lisp
systems do.
