Awesome! I've been looking for a followup to the previous paper, with no success. Thank you for posting it!
I skimmed through the paper and I don't see where they state the P1 prototype (or any prototype, for that matter) was "disqualified", as user mpweiher claimed. The authors continue to state they found Haskell and FP to be great for rapid prototyping... and in my opinion, anyone who's ever written a prototype will agree that making changes at short notice is expected :) And Haskell turned out to be very suitable for this. I think they were right to call it a success.
More importantly, that they were able to successfully (and with relatively little effort) generalize and extend the prototype shows that it was indeed extensible. That they were able to provide three prototypes is also telling, because even if some were delivered after the experiment, they were still made in a very short time. Imagine managing this feat in C++ or Ada!
It'd be interesting to see how many of the other teams which completed the assignment also had to implement some changes after the review.
