Announcing Lazy SmallCheck 0.1, a library for exhaustive,
demand-driven testing of Haskell programs.

Lazy SmallCheck is based on the idea that if a property holds for a
partially-defined input then it must also hold for all fully-defined
instantiations of that input. Compared to `eager' input generation 
in SmallCheck, Lazy SmallCheck may require significantly fewer
test-cases to verify a property for all inputs up to a given depth.

There is a webpage for Lazy SmallCheck:


There you'll find a more detailed description, a worked example, a
comparison with SmallCheck on a number of benchmarks, and link to
download the library.

The library was developed together with Fredrik Lindblad during his
recent visits to York.

Suggestions, experiences and bug reports are welcome!
