Description
Ideally the exception handling logic would be based off of either the exceptions or the monad-control package, but even a simple try :: (Exception e, Monad m) => PropertyM m a -> PropertyM m (Either e a) would be satisfactory.
I took a stab at each of these myself, but I couldn't get the types to work out. I'm creating this issue in hopes that there's something I missed that will be obvious to someone more familiar with QuickCheck's inner workings.

Research direction
The issue names PropertyM and the exceptions and monad-control packages but no files or tests. Start by locating PropertyM and its existing monad instances, then compare the requested try signature with those package APIs; done means a workable exception-handling interface is implemented and its behavior is covered by tests.
