Dear all, why is this allowed (GHCi, version 7.4.1): main :: IO () main = do let a, a :: Int a = 5 print a but this not: main :: IO () main = do let a :: Int a :: Int a = 5 print a Is there a deeper sens or is it just a little bit inconsistent?

[Haskell-cafe] types and number of evaluation steps
Dear all, I have a question about evaluation with respect to types and currying. Consider this programm: import Debug.Trace -- add :: Integer - Integer - Integer add :: Int - Int - Int add x y = x + y f a b c = trace b (add x c) where x = trace a (add a b) main :: IO () main = do print (f 1 2 3) print (f 1 2 4) Compiled with ghc-7.0.3: $ ghc --make Main.hs -o main -O2 The function add has to types. When we use type Int - Int - Int, the programm produces b a 6 b a 7 as output which shows that the x from the where clause in f is evaluated twice. However, when we use type Integer - Integer - Integer, this will give b a 6 b 7 which shows that x is evaluated only once. This was rather unexpected to me. Why does the number of evaluation steps depend on a type? Can anybody explain this or give a hint?

However, when entering nothing, instead of an empty string, I always get a string like /tmp/12101 which corresponds to an empty file.
