That seems nicer in that there is no raw loop, but it has two major drawbacks.

Consider this use of `find()`:
auto std::vector<int> vec = { 1, 1, 2 };
std::vector<int> vec = { 1, 1, 2 };
auto it = std::find(vec.begin(), vec.end(), 1);
This gives us the first occurance of `1` in `vec`. What if we want to find
the first occurrance of any number besides `1` in `vec`? We have to write an
unfortunate amount of code:
auto std::vector<int> vec = { 1, 1, 2 };
std::vector<int> vec = { 1, 1, 2 };
auto it = std::find_if(vec.begin(), vec.end(), [](int i) { return i != 1; });
With `find_not()` the code gets much more terse:
auto std::vector<int> vec = { 1, 1, 2 };
std::vector<int> vec = { 1, 1, 2 };
auto it = find_not(vec.begin(), vec.end(), 1);
The existing `find` variants are: `find()`, `find_if()`, and `find_if_not()`.
