This abstraction layer was not useful, so it is removed to simplify the
API around `ClassDefinition`.
A new method `ClassDefinition::type()` is also added, giving access to
the `ClassType` instance when working with a class definition.
Type aliases can now be imported from another class definition.
Both PHPStan and Psalm syntax are handled.
```php
/**
* @phpstan-type SomeTypeAlias = array{foo: string}
*/
final class SomeClass
{
/** @var SomeTypeAlias */
public array $someTypeAlias;
}
/**
* @phpstan-import-type SomeTypeAlias from SomeClass
*/
final class SomeOtherClass
{
/** @var SomeTypeAlias */
public array $someTypeAlias;
}
```
Type aliases can now be added to a class definition.
Both PHPStan and Psalm syntax are handled.
```php
/**
* @phpstan-type SomeTypeAlias = array{foo: string}
* @psalm-type SomeOtherTypeAlias = array{bar: int}
*/
final class SomeClass
{
/** @var SomeTypeAlias */
public array $someTypeAlias;
/** @var SomeOtherTypeAlias */
public array $someOtherTypeAlias;
}
```
