Hi all,
I've found and solved a problem with mime-mail, and Michael Snoyman
asked me to send a request for feedback to -cafe, so here goes.

I've noticed this too. I believe the issue is with the cairo bindings

Hi Cafe,
I only feel curious about what would be the consequences of becoming the
Overloaded Strings feature (currently, an extension) to be default in
Haskell. This is not a proposal. I just want to know what pros and
cons there are.
Thanks!

Yes, thank you. Here's my simple fix:
newtype Point = Point Int
instance Show Point where show (Point a) = [chr $ a + 48]
data Vector = Vector [Point]
instance Show Vector where
show (Vector ys) =
let show' [z] = show z
show' (x:xs) = show x ++ , ++ show' xs

Hi all,
Since the release of deepseq 1.2, we've had a bit of a problem: when
using the newest versions of packages on Hackage, there is no NFData
instance available for the containers types. When GHC 7.4 comes out
with its newer version of containers, this will be addressed, but
we'll still have
