@KenoFischer @PjdPeter @gregkh @johnregehr Yes! This was an IRB 'failure'. Again, in my area of Social Computing, it's been clear for awhile that IRBs often do not understand the issues and the potential risks/harms of doing research in online communities / social media. So researchers have to exercise their own care....

Types: p_0 :: Show a => (a -> Bool) -> IO [a] -> IO () p_1 :: Show a => (a -> Bool) -> IO [a] -> IO () p_2 :: (Foldable t, Show a) => (a -> Bool) -> IO (t a) -> IO () p_2's other, derived type ignores the predicate: p_2 :: (Foldable t, Show a) => b -> IO (t a) -> IO () 😆

Evolution of "p_k p = print each until p (pred) gives False" in #Haskell: p_0 p = mapM_ (\(i, x) -> if p x then print (i, x) else error (show (i, x))) . zip [0..] p_1 p = foldM_ (\ i x -> if p x then print (i, x) >> return (i+1) else error (show (i, x))) 0 p_2 _ = mapM_ print

popl18.sigplan.org/event/popl-201… I've been discouraged from writing random tests in Ruby. I like the QuickCheck approach and deterministic tests are limited, but maybe if failing random tests were added to a list of static tests, we could prevent patterns like: ✓ x ✓ x x ✓ ✓ ✓ x x ✓

How is it so fast? "Instead of a hybrid brute-force approach".."there is a relentless positional boa constrictor approach that is simply unheard of." It avoids dead-ends by having "no such..issues, and seems to thrive on snuffing out the opponent’s play.": youtu.be/p20TBm_H5K8
