Thanks very much. I'm slightly embarassed: what I meant was that I would
add the paragraph if you thought it was worth doing.

I suppose its priority depends on how many people start to get tripped
up. I'm guessing there aren't that many GADT users who don't know (by
now at any rate) how to understand the error messages. I'm sure there
are plenty of higher priority items.
