Hm. It is indeed also a modernization... +- on which to pick. Let's see what
others think.
On one hand, the modernize checks have
- modernize-use-auto
- modernize-use-nodiscard
- modernize-use-noexcept
- modernize-use-override
- modernize-use-using
while the misc category has `misc-const-correctness`, which is also close to
this check. Though, `constexpr` also provides additional benefits and not just
modernization. It can provide additional safety checks if UB would be
encountered at compile-time, e.g.,
```c++
constexpr int div(int a, int b) { return a / b; }
int main() {
constexpr auto res = div(10,0);
return 0;
}
```
, or potential performance improvements.
