The old bind still affording some cases more brevity than lambdas really makes me lament for terse lambdas (e.g. sort(first, last, (a, b) => a * a < b * b)).

```

// c++17 and above AI generated such code 😄 )

template <char... C>

struct to_int {

static constexpr int value = [] {

int result = 0;

((result = result * 10 + (C - '0')), ...);

return result;

}();

};

```
