Re: Panic when using syb with GHC API

Hi Pedro,

If it seems like this avoids the problem, I'd be happy to release a new version of SYB containing these type-guided traversals.

Do you think it would be a good idea to make the interfaces of Data.Generics.GPS and Data.Generics more similar? One thing I have noted is, that Data.Generics exports Data.Data, but Data.Generics.GPS does not. Cheers, Simon
