Congratulations on the new release. But out of curiosity, I've got to ask...

Why is the test suite now driven by a python script? Is this a niche where a 'scripting' language was deemed more suitable than haskell?

The test driver makes use of 'eval'-style scripting, which none of the existing Haskell systems has. Template Haskell does provide a kind of 'eval', but it is compile-time rather than run-time. That's interesting though: I hadn't thought about it, but it might be possible to implement the test framework as a Haskell library which uses Template Haskell. Cheers, Simon
