DEPRECATED foldWithKey "Use foldrWithKey instead"

Hi, I find this particular warning (in the subject) unjustified and annoying. Could someone (maybe the person who introduced it) simply delete it in the next version (or make a library proposal)? A matching "foldrWithKey" (and foldlWithKey) is missing in Data.IntMap. and folding without keys is also only given via "fold" in Data.Map. Data.Set contains toList and toAscList and the former is rightly not deprecated. (A function toDescList is missing though in Data.Set.) Furthermore, Data.Map.foldrWithKey is not part of the container package that came with ghc-6.10.4. Cheers Christian
