 Prepare library for the next major version 
Version 3.0 will include a few crucial deprecations. This commit adds
some soft deprecations to warn users about these changes.

Some of the biggest changes are:

* The method `validate()` will be renamed to `isValid()`.

* The method `validate()` will be repurposed to return an object with
  failures.

* It won't be possible to handle rules directly; users will need to use
  the `Validator` class to validate with any rule.

There will some more changes, but those are some of the most important
ones, and are the ones that are easy to deprecate right now.

Raw Blame History

When

  • When(Validatable $if, Validatable $then)
  • When(Validatable $if, Validatable $then, Validatable $else)

A ternary validator that accepts three parameters.

When the $if validates, returns validation for $then. When the $if doesn't validate, returns validation for $else, if defined.

v::when(v::intVal(), v::positive(), v::notEmpty())->isValid(1); // true
v::when(v::intVal(), v::positive(), v::notEmpty())->isValid('not empty'); // true

v::when(v::intVal(), v::positive(), v::notEmpty())->isValid(-1); // false
v::when(v::intVal(), v::positive(), v::notEmpty())->isValid(''); // false

In the sample above, if $input is an integer, then it must be positive. If $input is not an integer, then it must not be empty. When $else is not defined use AlwaysInvalid
