Also, this | bug in particular looks like it manifests in a fairly nasty way, and | having it catch people for the final release seems a bit worrisome. | | I also just remembered that the Haddock documentation for 7.10.1 is | still broken; I've been tracking the bug today, but I need to sync up | with the Haddock maintainers to discuss more. I really think this one | needs to be fixed. | | So I also suggest we postpone for a few days to fix these two things, | if possible. | | On Sat, Mar 21, 2015 at 6:55 AM, Neil Mitchell <[email protected]> | wrote: | > Interesting result.
