Hi,
I'm going to add Type Families support to the Haddock HTML backend. What would be the best way to do it? I'm thinking it could work similar to how classes and instances are currently rendered, so that type/data/newtype instances are collected and attached to type family declarations. Is this too simplistic? Should we render type/data/newtype instances as separate entities in the module documentation instead (and perhaps do the same thing with class instances)?
Currently, when packages export instances that belong to classes from other packages, those instances are not documented anywhere. An advantage of having instances as separate entities in the exporting module documentation is that no instances are "lost".
Please go for it! I need type families support for the uvector documentation to build.

Yes, I didn't bother to add proper error messages for unsupported syntax, so that's why some packages that use e.g. type families just die with pattern matching failures. I'm adding support for more syntax now, and I'll try to add proper error messages if I come across something that won't be supported. David
