How to get field value in message creator function?

[zoxon]

Thank you for this library.
I'm trying to create a custom validator using createValidator helper
In the message I need use current value, how to achieve this?

It looks something like this

const myValidator = createValidator(
  message => value => message,
  (field, value) => `${field} has value ${value}`
);

Experiments today and find that.
Return function instead of string, and apply value in validator implementation.
What pitfalls are there?

const myValidator = createValidator(
  message => value => message(value),
  (field) => (value) => `${field} has value ${value}`
);
