[Haskell-beginners] State monad and destructive updates

[Rohit Garg]

Hi,

As I have been trying to learn the monads a bit more, I have come to
realize that State monad doesn't actually represent state. It just
provides a convenient glue for threading state. Is that correct? If
so, then for performance using state monad is as good as not using it
at all. Is there a way to have state with destructive update?

Thanks,
