[Haskell-cafe] GHC + interactive input/output

[Jonathan Cast]

$ cat > foo.c
#include <stdio.h>

int
main()
{
   char s[1024];
   printf("gsi> ");
   gets(s);
   printf("%s\n", s);
   return 0;
}
$ make foo
cc     gsi.c   -o gsi
$ ./foo
warning: this program uses gets(), which is unsafe.
gsi> hello
hello
$ cat > foo.hs
main = do
   putStr "gsi> "
   s <- getLine
   putStrLn s
$ ghc foo.hs -o foo
$ ./foo
hello
gsi> hello

(This is on MacOS X).  It strikes me that GHC is being  
extraordinarily unhelpful here.  Is there anyone on the planet who  
ever actually wants this behavior?
