    Make a generic function which calls a validator with the right arguments.

    Unfortunately other approaches (eg. return a partial of a function that builds the arguments) is slow,
    hence this laborious way of doing things.

    It's done like this so validators don't all need **kwargs in their signature, eg. any combination of
    the arguments "values", "fields" and/or "config" are permitted.
