Good idea. I added a ticket.
http://cvs.haskell.org/trac/ghc/ticket/792
If there is no taker I'll try to do it this weekend.
Cheers,
JP.

It bothers me that the functions findMin, findMax, deleteFindMin and deleteFindMax are error when applied to the empty set in various types of collections. Shouldn't they return Maybe?
FYI, Edison has operations that generalize 'deleteFind*' (named viewMin/viewMax) which call 'fail' in an arbitrary monad when applied to an empty collection; obviously, these can be instantiated at type 'Maybe'.
