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

[John D. Ramsdell]

I couldn't find the mkHandle function in the source linked to the
specified Haddock generated documentation page.

If there is a consensus that others besides myself would like a
function with the signature

stringHandle :: String -> IO (Handle)

I'd be happy to contribute code.  I'd need help as I haven't ever
contributed this kind of code.
