Two questions on module ST: http://www.haskell.org/ghc/docs/latest/set/sec-st.html

In any decent implementation, yes. -- Fergus Henderson | "I have always known that the pursuit The University of Melbourne | of excellence is a lethal habit" WWW: http://www.cs.mu.oz.au/~fjh | -- the last words of T. S. Garp.
