In a nutshell

class T {
  public const string NAME= 'Test';
}
  • Syntactic support with erasure at compile time (see cad16ee)
  • Emit type in meta information for PHP < 8.3
  • Extend reflection to support types for class constants
  • Emit types once the Typed class constants RFC implementation is merged into PHP 8.3

The RFC has been accepted, need to wait for php/php-src#10444 before adding this to the PHP 8.3 emitter.
