[Haskell-beginners] Re: the role of assignments

[edgar klerks]

He Prad,


 do line <- getLine
    putStr "You entered: "
    putStrLn line

The example of Ertugrul is desugared to the following:

getLine >>= \x -> putStr "You entered: " >> putStrLn x

or even:

getLine >>= \x -> putStr "You entered: " >>= (\_ ->  putStrLn x)


It helps a lot to not use the sugared syntax, until you know how to write
them without the sugar. That way you will grasp the concept of monads much
faster.

it is also a matter of taste, for small monadic functions I prefer the
desugared style.  For longer it becomes a bit unwieldy.

Greetings,

Edgar
