I use these instances and similar ones from NumInstances [1] quite a bit. I
also frequently use another pattern for applicative functors, via
applicative-numbers [2]. I don't mind pulling these instances from a
package, though they are orphans.
It does trouble me a bit that the two patterns overla

I often have to rewrite the signature of foldl to the suggested version as
a sanity check. I thought it just was my personal mental deficiency.
I prefer "b" to "r".

I see that this this trac item has no milestone and an "unknown" duration.
Has this problem (incompatibility of large libraries and ghci on the Mac)
slipped through the cracks? Is it thought to be unimportant? For me, not
being able to count on ghci is a huge detriment. Thanks,

On Sun,
Are there plans for running the new base libs (and perhaps extras) through
haddock 2.0? The new & old .haddock files are incompatible, so running
haddock 2.0 isn't resolving base lib links. - Conal

I get this very same error on a clean build with STABLE ghc-6.8.20070909 (on
Windows). Any ideas on what's going wrong here and how to fix it?

I don't know if the build gods are looking for who-cares-about-what input,
but if so, i'd love to have a recent build of ghc HEAD that works on
windows. i haven't found one yet, and i'd really like to so i can compile &
run haddock 2.0 and then release several packages. The 20070824 was so
close,
I get the following error while linking haddock.ghc using the snapshot
ghc-6.7.20070824-i386-unknown-mingw32.exe .

No big deal after all. Replacing the ($) uses with regular parenthesized
application allows compilation to go through. - Conal

In going from ghc-6.6 to ghc-6.7, I've lost some GADT pattern matching that
I'd really like to have back. The message:
c:/conal/Haskell/Eros/src/gadt-example.hs:23:32:
GADT pattern match in non-rigid context for `:*'
Tell GHC HQ if you'd like this to unify the context

I'm running ghc-6.7.20070802 and getting a new error message that didn't
show up with ghc-6.6. Code:
-- | Pairing for unary type constructors.
newtype Pair1 f g a = Pair1 {unPair1 :: (f a, g a)}
deriving (Eq, Ord, Show)
Error message:
src/Data/Tupler.hs:26:0:
No instances
I installed ghc-6.7.20070810-i386-unknown-mingw32.exe. Though it runs, I
don't know how to get other packages installed, including Cabal. "ghc-pkg
list" tells me that I have only {ghc-6.7.20070810}, rts-1.0.
Any suggestions?
Thanks, - Conal
