Tests:

Using `R.where`
pred1({a: "foo", b: "xxx", x: 11, y: 19}) pred1({a: "xxx", b: "xxx", x: 11, y: 19}) pred1({a: "foo", b: "bar", x: 11, y: 19}) pred1({a: "foo", b: "xxx", x: 10, y: 19}) pred1({a: "foo", b: "xxx", x: 11, y: 20})
Using `whereAll`
pred2({a: "foo", b: "xxx", x: 11, y: 19}) pred2({a: "xxx", b: "xxx", x: 11, y: 19}) pred2({a: "foo", b: "bar", x: 11, y: 19}) pred2({a: "foo", b: "xxx", x: 10, y: 19}) pred2({a: "foo", b: "xxx", x: 11, y: 20})
