@klausler I did try to come up with an error message that included the actual value that was passed, but I couldn't come up with any message that was concise or that I liked better than the current error message. I am of course open to suggestions. And thank you for your feedback on the better way to access the object inside of an `std::optional`.

@jeanPerier Thank you for your helpful suggestions on how to unpack the `Expr<SomeType>` if it was an array. I have unpacked it now and was able to provide an error message if a non positive value is included in the array. There might be a more elegant way to deal with all of the different `kinds`, but this is what I have come up with for now.
