Re: [Yhc] ByteString

Hi Creighton,

This might be a silly question for you guys, but is there a reason why yhc still uses PackedString in places instead of ByteString?

Two reasons: 1) ByteStrings are totally unreliable - they can't be made to work in GHC 6.4 and GHC 6.6 without features of Cabal that aren't even written yet. We did move to Data.Binary, which requires ByteStrings, but had to change back because it was a nightmare. If the benefits were compelling we could move, but it wasn't worth it just for binary serialisation. 2) When the code was written, there weren't ByteStrings, and no one has had the time to port to them. If someone ported Yhc to ByteStrings, we'd definitely accept a patch! Thanks Neil
