==Haskell: No variable?== I'm afraid the current Haskell example (putStrLn ("Hello" ++ "World")) misses the point: it shows how to append one string onto another and print the result, not how to assign a variable and update it by prepending a string. : You are right! I guess functional languages don't go much for mutable state, but that is what the task requires... :--[[User:Paddy3118|Paddy3118]] ([[User talk:Paddy3118|talk]]) 08:54, 13 February 2015 (UTC)
