Indeed, it would be nice to have both the client-side and server-side
validation, error messages etc. with the same one piece of Racket code. For
user experience and security it needs to be done in both ends anyway. Seems
like one motivation for a DSL for validation.

However, can it be general enough to cater to different JS-frameworks too?
