>Is this part correct? ValueTypeSubset v1 = v; not ValueTypeSubset v1 =
int64_t{1};?
Regarding this, I mean first creating an object of type
std::variant<int64_t, double>, and then assigning it to a std::variant<int64_t,
double, std::string> object.
Such an assignment is not directly possible with std::variant, but it is
allowed with the Boost version.
However, since this kind of conversion would only happen in the internal
implementation, I think it's fine to stick with a simple converter function
like the one below.
```c++
ValueType ConvertToSuperSet(ValueTypeSubset value) {
return std::visit([&](auto v) {
return ValueType(v);
}, value);
}
```
