[Haskell-cafe] Top-level state debate on the wiki

Ben Rudiak wrote (snipped):

I put up a wiki page summarizing the main proposals for top-level mutable state. The type-dictionary approach isn't there yet, but there's a space for it; I'll probably fill it in within the next 24 hours unless someone else feels like doing it first.

Please add more detail, objections, examples. Especially examples!

Here's the page:

http://haskell.org/hawiki/GlobalMutableState

I have added a summary of the type-dictionary approach. I recommend other people look at this page and, if there is something they disagree with, amend it so that their own view is reflected. IMO the WiKi approach is an excellent way of obtaining consensus and providing an overview of the topic.
