This is deliberately private, as I do not want to guarantee the type being stored.

Suggest then how to customize the error message. How to get what range is incorrect?
For example, in the current display implementation, you print the range as 1..=30, but this does not look good for the user interface.

Currently, you cannot obtain the range of validity, at least easily. I suppose you could work from the component name and whether it's conditional to determine the name, but that's about it.
