What is the intended use case? Since many uses of Ord imply filtering 
out duplicates, this seems like it could result in getting inconsistent 
capitalization. Granted, the RFC says it's case-insensitive, but some 
folks like their aesthetics... (then again, those folks should probably 
use case-normalizers. I'm mostly just curious if the Ord is intended for 
Data.Map or what.)

Live well,
