This is cool, but not really the problem I have, nor many I've talked to have when actually doing something 'real' in Haskell. (Granted we're a rare breed, actually trying to use Haskell for real-world use outside academia) Show me how much memory a program will actually use. If it uses a lot, show me why it did, and where it did. This is a solved problem for most mature languages, and the lack of tooling making it even remotely possible to figure this out in Haskell speaks volumes about how ready it is for "real world use".
