> The only server side validation we do for values is currently that they match their type. Now that we have UDFs, we could allow to optionally specify a (boolean) value validation function on a per-column basis. This would give us a pretty generic way of validating value, which sounds useful to me.
> Once we have that, we could even add some syntactic sugar for some common type of validations, like {{v int[0..100]}} for numbers between 0 and 100, or {{v text[20]}} for a string that is not longer than 20, ... That's more of a follow up however.
