[plt-scheme] Formlet error handling and validation?

I don't think we have what you are looking for.

The to-... functions throw errors if the values cannot be coerced, but
this is not automatically reflected back to the Web user.

It would be an interesting library that did that, and I think it would
be sensible to do it in the formlet system, but it doesn't yet exist.
