Dear libraries at ...,

Shouldn't Control.Monad.ST export ioToST :: IO a -> ST RealWorld a, as
defined in GHC.IO?

Hugs for some reason does not have it, but it would seem trivial to
write, given their stToIO:

stToIO              :: ST RealWorld a -> IO a
stToIO (ST f)        = IO f

It doesn't look like anyone else even *has* ST...
