ReferenceError / Instance prototype not found

[dpomier]

The following sample yields on js and eval but not on hl or neko (Haxe 4.3.1 on https://try.haxe.org/#02bf26bF):

class Test {
	static var sub = new Sub();
	static function main() {}
}

@:keep class Sub extends Test {
	public function new() {}
}

JavaScript yields:

ReferenceError: can't access lexical declaration 'Test' before initialization

Eval yields:

[WARNING] Test.hx:1: lines 1-5

 1 | class Test {
 - |   [...]
 5 | }
   |
   | (WStaticInitOrder) Warning : maybe loop in static generation of Test

[ERROR] Test.hx:1: lines 1-5

 1 | class Test {
 - |   [...]
 5 | }
   |
   | [0] Instance prototype not found: Test

That code looks like you should get this warning on all targets... I wonder why only eval emits it.

Other than that I don't think there's anything to fix here.

Why would this be a loop? I would accept that Sub needs to know the structure of Test to be able to extend it, but it does not need to know the static fields, because these are not inherited.

This depends on the generators, if all of them are fine with this then I agree we can make this work for JS and eval too. I would still like to know why that warning is target-dependent because the logic should be the same for all targets.
