Part of my current interest in #2 is that I have been experimenting with some full-program optimization algorithms which could perhaps give substantial gains but would pretty much obliterate any uses of the unsafePerformIO global variable hack, and no pragma can save them. Before this, I never realized just how uncorrect the global variable use of unsafePerformIO was :)
That sounds fascinating. Can you say more about the optimizations in question, and why the hack is so incorrect? Peace, Dylan
