"Integer" looks like a reserved keyword

[Zekfad]

Following code produces errors while it shouldn't:

class Integer {
	public function a(): Integer // 'ReturnType' expected // '{' expected
	{ // '}' expected
		return $this;
	}
}

I am currently traveling and can't check this yet. But do try public function a(): self instead of Integer.

Does the problem also happen if the class name is something else, not Integer?

Best!

self produces no error, but that's still an issue, because it's a false error report for a valid PHP code.

I haven't tested other names like that yet.
