Re: Proposal: containers: add indexing operations for Set

Hi,

I'd like to add the following indexing operations for Data.Set.Set, to complement the existing functions for Data.Map.Map:

findIndex :: Ord a => a -> Set a -> Int lookupIndex :: Ord a => a -> Set a -> Maybe Int elemAt :: Int -> Set a -> a deleteAt :: Int -> Set a -> Set a
