IO reordering
I have a simple test program:
main = do putStr "> "
line <- getLine
putStrLn lineIn ghci, it writes "> " before receiving input:
Prelude Main> main
> WHAT
WHATBut being compiled by ghc it writes "> " just after receiving input.
maelstrom@ubuntu:~/vault$ ./test
WHAT
> WHATThat is not the behavior I expect.
