I know that you can define the powerset to be a function $P : V\_\kappa \rightarrow V\_{\kappa +1} $ where $V\_{\kappa}$ is a stage on the Neumann universe, but recall that the stages o... | 2018/03/18 | [

Thus defining the power set as a function requires some domain different from the collection of all sets.
The power set is well defined but as if we try to define power set as a function with a domain and a codomain we will get into paradoxes. |

] | You cannot pass a temporary resulting from converting the `Foo` to a `std::variant<Foo,Bar>` to `f2`. C++ disallows this because binding a temporary to a non-const reference is most likely a bug. If it was possible you'd have no way to inspect the modified value anyhow.

It seems you use `std::variant` to restrict possible argument.
If that is the case, template might be an alternative solution:
```
template <typename T>
constexpr bool isFooBar = std::is_same_v<T, Foo> || std::is_same_v<T, Bar>;
template <typename ... |
