looks like a light weight version of lens.
Data.Label seem to be another approach (fclabels package)

I would love to stay away from all the lens libraries for a while

I managed to get code navigation work quite nicely with codex.
cabal install codex
cabal install  hasktags (the debian package is something else)
# Add `tagsCmd: hasktags --etags --output="$TAGS" "$SOURCES"` to ~/.codex
cd project
codex update
M-x visit-tags-table 
Works with all the additional packages listed in the cabal file. Very nice :)

Useful to quicky see definitions from stdlib. See liftM for example. simple and elegant
-- | Promote a function to a monad.
liftM   :: (Monad m) => (a1 -> r) -> m a1 -> m r
liftM f m1              = do { x1 <- m1; return (f x1) }
