Dear haskeller,
Can I destructive rebind a local variable like this
import System.Directory
test filename = do
is_dir <- doesDirectoryExist filename
let filename = if not is_dir then filename else filename
putStrLn $ " filename " ++ filename
main = test "."
in GHCi 6.10.1 on WinXP, the ghci aborts silencely when I executes
"main"
after compile it into a executable file.
c:\USERS\home\learning_haskell\>testDirectory
testDirectory
C stack overflow in generated code
I have some code in scheme which works very well
(define (func x)
(let ((x x))
x))
By rebinding a formal variable, we can save naming some varaibles. I
am not good at naming a variable.
Thank you in advance
Best Regards
Chunye Wang
