Could you add your comment to the ticket I've created?

As for case conventions: The parts of GHC I play in have a fairly reliable convention: underscores for local things (both local variables and non-exported helper functions) and camel case for exported things. It's a nice convention that I've used elsewhere. This is not rigorously applied, but it's pretty good.
