The function must work if one change a to let x=2:x in x, let x=1:2:3:x and variations on the same theme.
Can Java, C?
I think most of us can write a C program that can print circular lists.
What do you mean by 'notation'?
I might have used the wrong word. Can you write the NUMBER 1 on a piece of paper ? I think you cannot. You must use some encoding for it. The same thing with let x = x in x. How can one print numbers in Haskell ? I don't understand. When I say print (2+4), why 6 is printed and not 10 - 4 ?
Would main = do txt <- readFile "Module.hs" let definitions = parseModule txt case lookup "a" definitions of Nothing -> putStrLn "No definition for a" Just rhs -> writeFile "Notation.hs" (prettyprint rhs) satisfy you?
Yes, but there is a little problem with 'txt<- readFile "Module.hs" and case lookup "a" ... ' You see, I don't know if I must print a or b. ________ Information from NOD32 ________ This message was checked by NOD32 Antivirus System for Linux Mail Servers. part000.txt - is OK http://www.eset.com
