Hi Cafe,

Is there a reason that the GHCi interpreter doesn't detect and report infinite loops in statements like this (like compiled programs do) even though no CPU time appears to be used? My (admittedly weak) searching for an answer didn't turn much up.

let s | not $ null s = [] in s

GHCi v7.0.4 on OSX

Thanks, John

Hi John, I think this is a known problem in GHCi: http://hackage.haskell.org/trac/ghc/ticket/2786 Regards, Michal
