I've uploaded my CMonad package to Hackage.  It allows you to write
Haskell code in a C style.
Unfortunately, GHC lacks certain optimizations to make efficient code
when using CMonad,
so instead of C speed you get low speed.

Example: Computing some Fibonacci numbers:
fib = do {
   a <- arrayU[40];
   i <- auto 0;
   a[0] =: 1;
   a[1] =: 1;
   for (i =: 2, (i :: EIO Int) < 40, i += 1) $ do {
       a[i] =: a[i-1] + a[i-2];
   };
   retrn (a[39]);
 }


Example: Copying stdin to stdout:
cat = do {
   c <- auto 0;

   while ((c =: getchar()) >= 0) $ do {
       putchar(c);
   };
   return ();
 }
