Just another data point. I'm fumbling around with Arrays these days
(see my recent post on haskell-cafe) and thought I'd try DiffArray.
After all, I'm building large lists of index/values, and applying (//)
to them.
Now, the docs on how to use DAs aren't all that extensive, but I
replaced the type signatures, and at least the type checker is happy.
However, quickCheck (great tool) just prints a digit and hangs there.
Running the compiled program gave:
sefirot% !nice
nice time ./a.out +RTS -p -h -K16M
Fail: thread blocked indefinitely

I'm probably missing something essential, any idea what it might be?
