I'd like to use QuickCheck on IO code. For instance, I'd like to
check a property of type String - IO Bool.
Using unsafePerformIO seems straightforward (though I haven't written
the code, so I may be wrong about that) and it might be possible to
make a solution involving unsafeInterleaveIO

Barring that, I suspect it's possible modify QuickCheck to accommodate
IO code (or perhaps, general monadic code). Has anyone done this?
Yes,
I found the code at:
http://www.cs.chalmers.se/~rjmh/QuickCheck/QuickCheckM.hs
The only deconstructor there for PropertyM requires a run function
of type m Property - Property. For IO, run is unsafePerformIO.
-m
