Allow to apply the same validating ruleset to multiple attributes

What steps will reproduce the problem?

It is impossible to apply the same set of rules to multiple attributes of an object or an array.

What is the expected result?

Would be really useful to be able to apply same set of rules to multiple attributes at the same time (like it was in Yii2). Coulb be done with something like:

$rules = [
    new Some(['email', 'emailConfirmation'], [
        new Required(),
        new Email()
    ]),
];

or

$rules = [
    new Some(['field1', 'field2', 'field3', ...], new Required()),
];

What do you get instead?

Now I need to duplicate code like this:

$rules = [
    'field1' => new Required(),
    'field2' => new Required(),
    'field3' => new Required(),
    ...
];

Additional info

The issue names no implementation files or tests. Start by locating how rules are assigned to attributes and how existing Required and Email rules are tested; define coverage for applying one ruleset to multiple attributes and verify each named attribute receives the expected validation.
