passing an accumulating parameter from left to right, and returning
a final value of this accumulator together with the new structure.

The mapAccumWithKeyR
function behaves like a combination of mapWithKey

passing an accumulating parameter from right to left, and returning
a final value of this accumulator together with the new structure.

foldMapWithKeyDefault :: (TraversableWithKey t, Monoid m) => (Key t -> a -> m) -> t a -> m Source #
