Comment:
Very true.
Would anyone like to look at the overlapping-pattern warnings? It's a
well-defined problem, restricted to a single module in GHC
(`deSugar/Check.lhs`). We have a bunch of tickets about it: at least
#595, #5728, #3927, #5724, #5762, #4139, #6124.
A lovely project awaits!
Meanwhile I think I'll leave the code in its simplified state.
Simon
