We are in need of a proper name!

Trying to get Cerberus.

It would be nice if it was possible to pipe validated values through a function. After the validation, the given function would be applied to the result and the result would be returned.

As an example, say I'm using an immutable list which offers a fromArray function that converts arrays into immutable lists. It would then be very convenient if I could apply this conversion as the same as the validation takes place. Here is an example:

const person = object({ name: string, id: number });
const schema = person.extend({
  mother: person,
  father: person,
  children: array(person).thru(fromArray)
});

It would also be nice if this processing could come first in the validation as a way to sanitize input.

const person = object({
  name: string
  // Buggy API users sends numbers as strings :'(
  age: thru((n) => parseInt(n, 10)).number.gt(18)
});

The name thru is inspired by this thru. Other ideas for a name: process, convert, sanitize, transform.

We want to be able to validate asynchronously.

number.mapAsync(fetchUserNameById/*(id: number) => Promise<string>*/).includes("foo");

How do I use it? 😄

Need to update the readme, perhaps separate the API documentation.
