Hi,

I am trying to run the following from the GHCi command prompt which results in parse error.

--------------
Prelude> :{
Prelude| foo :: Maybe String
Prelude| foo = do
Prelude| x <- Just 3
Prelude| y <- Just "!"
Prelude| Just (show x ++ y)
Prelude| :}

<interactive>:145:5: parse error on input `='

Any help would be appreciated.

Thanks,
Shishir
