Attributes to define PHP language extensions (to be enforced by static analysis).

This library provides attributes that are used by static analysers to enforce new language features. The intention, at least initially, is that these extra language features are enforced by static analysis tools (such as Psalm, PHPStan and, ideally, PhpStorm) and NOT at runtime.

Valinor takes care of the construction and validation of raw inputs (JSON, plain arrays, etc.) into objects, ensuring a perfectly valid state. It allows the objects to be used without having to worry about their integrity during the whole application lifecycle.

The validation system will detect any incorrect value and help the developers by providing precise and human-readable error messages. The mapper can handle native PHP types as well as other advanced types supported by PHPStan and Psalm like shaped arrays, generics, integer ranges and more.
