Exporting ioToST from Control.Monad.ST

There's a function stToIO that is defined in GHC.IO and exported from Control.Monad.ST. There's another function, ioToST, that's also defined in IO, but it isn't exported from Control.Monad.ST. I propose that it be exported from Control.Monad.ST. -- -Andrew Thaddeus Martin
