Lazy([6, 29, 1984]).join("/")  // => "6/29/1984"
Lazy(["a", "b", "c"]).join()   // => "a,b,c"
Lazy(["a", "b", "c"]).join("") // => "abc"
Lazy([1, 2, 3]).join()         // => "1,2,3"
Lazy([1, 2, 3]).join("")       // => "123"
Lazy(["", "", ""]).join(",")   // => ",,"
Lazy([1, 2]).join(0)           // => "102"
Lazy(["cons", "d"]).join(true) // => "construed"
Lazy({foo: 1, bar: 2}).values().join()        // "1,2"
Lazy({foo: 1, bar: 2}).keys().join()          // "foo,bar"
Lazy({foo: 1, bar: 2}).map(toParam).join('&') // 'foo=1&bar=2'
