[Hugs-users] wrong infered types?

[Paqui Lucio]

Hi, 
In Hugs, the infered types for the following four functions: 
f a = let m = id a in do return m 
f' a = do m <- id a 
          return m 
g a = let m =[a,a] in do return m 
g' a = do m <- [a,a] 
          return m 
respectively are 
f :: Monad a => b -> a b 
f' :: Monad a => a b -> a b 
g :: Monad a => b -> a [b] 
g' :: a -> [a] 
I didn't expect this types, do you? 
Anybody has some explanation? 
Thanks in advance, 
Paqui
