[Haskell-cafe] How does one create an input handle bound to a string instead of a file?

[Bob Ippolito]

I haven't had time to make an example yet but it looks like if you go down
to GHC.IO.Handle.Internals there's a mkHandle function that takes a
BufferedIO and some other stuff and gives you an IO Handle.
