This package provides
Getter that are fully compatible with lens; the downside is that this package depends on contravariant, which in its turn depends on a lot of other packages (but still less than lens).
The difference between
SimpleFold is that you can use e.g.
backwards on the former but not on the latter. Most functions from lens that work with
Fold would work with
SimpleFold as well, tho.
