ghc actually provides a primop for this:
reallyUnsafePtrEquality# :: a -> a -> Int#
Use at your own risk.
Why is it more than unsafe? 'unsafePerformIO' seems to me a lot unsafer than 'reallyUnsafePtrEquality#'. Also, is anybody using 'reallyUnsafePtrEquality#' on a working project? Cheers, -- Felipe.
