The template `valueTypes` stores all types of the member values and uses SumTypes's `get` function, which returns a `ref`. However, ref does not persist and the type is not sent to `canMatch` as a `ref`. Because of this, when matching, `canMatch` will fail as it will test for a copy, and returning a reference of that value results in escaping it.
