> Hi all,
> The HappS version on Hackage does not yet support ghc 6.10, since GADT
> pattern matching and the Exception API have changed.
> One sample error is:
> src/HAppS/Data/Xml/Base.hs:281:23:
> GADT pattern match with non-rigid result type `t1'
> Solution: add a type signature
> ...
> Adding a type signature via an auxiliary function instead of a case
> expression, the problem goes away.
> readElementRigidity :: (Monad m,Xml t) => Rigidity m -> m ([Element],t) ->
> Maybe t
> readElementRigidity Rigid m = ...
> readElementRigidity Flexible m = ...
> Is there a plan to update the version on Hackage to support ghc 6.10.1?
> I don't know either if it may break backwards compatibility.
