Test.IOSpec Version 1.0
I'm pleased to announce the first release of the Test.IOSpec library,
that provides a pure specification of some functions in the IO monad.
This may be of interest to anyone who wants to debug, reason about,
analyse, or test impure code.
Essentially, by importing libraries from IOSpec you can the same code
you would normally write in the IO monad. Once you're satisfied that
your functions are reasonably well-behaved, you can remove the
Test.IOSpec import and replace it with the "real" functions instead.

Tarball: www.cs.nott.ac.uk/~wss/repos/IOSpec/dist/IOSpec-0.1.tar.gz
Haddock: www.cs.nott.ac.uk/~wss/repos/IOSpec/dist/doc/html
Several examples are included with the sources.
At the moment, the library consists of the following modules:
* Test.IOSpec.Teletype: a specification of getChar and putChar.
* Test.IOSpec.IORef: a specification of most functions on IORefs.
* Test.IOSpec.Concurrent: specification of forkIO and MVars.
As an added feature, running concurrent code using
Test.IOSpec.Concurrent will detect deadlocks, instead of looping
indefinitely.
Future work includes:
* Improving the interface, making it easier to combine functions
from different modules.
* Adding more functionality: STM and weak pointers seem likely
candidates.
If you have any questions, comments, or feedback, please do get in
touch.
