Are the following two functions equivalent? (i.e. do they describe the
same computation)

let add1 a  = a + 2
let add2 = \ a -> a + 2

:t add1
add1 :: forall a. (Num a) => a -> a

:t add2
add2 :: forall a. (Num a) => a -> a


Does Haskell interpreter convert all functions in the form of add1 to
the lambda form of add2?

Does this lambda form represent the operational semantics of Haskell?


How should I translate the type information into English?


Thanks
Pat
