I'd also like to point out that this doesn't cause a fatal error, at
least in the latest RC (I haven't tried the official release yet).
trait Foo
{
public const CONSTANT = 1;
public function bar(): int
{
return self::CONSTANT; // Fatal error
}
}
class Bar
{
use Foo;
}
var_dump(Bar::CONSTANT); // 1
var_dump((new Bar)->bar()); // 1
