Need a check that will find cases where `std::vector` is used redundantly for **fixed-size, statically initialized data**. The check will suggest a replacement with `std::array` for better performance and clarity.
BEFORE:
```
bool foo(int val) {
std::vector<int> v = { 1,2, 5, 10, 33 };
return std::range::find(v, val) != v.end();
}
```
AFTER:
```
bool foo(int val) {
std::array<int, 5> v = { 1,2, 5, 10, 33 };
return std::range::find(v, val) != v.end();
}
```
In C++17 mode the check will produce replacement with CTAD usage:
```
bool foo(int val) {
std::array v = { 1,2, 5, 10, 33 };
return std::range::find(v, val) != v.end();
}
```
