Overriding coroutines does not work

[Simn]

import hxcoro.CoroRun;
import hxcoro.Coro.*;

class Parent {
	public function new() {}

	@:coroutine public function test() {
		trace("Parent.test() 1");
		yield();
	}
}

class Child extends Parent {
	@:coroutine override function test() {
		trace("Child.test()");
		super.test();
	}
}

function main() {
	CoroRun.runScoped(node -> {
		new Child().test();
	});
}

This endlessly calls the two test functions. The problem is that invokeResume from Parent.test invokes Child.test instead because the normal OOP dynamic dispatch comes into play.

I think we have to disallow this.

Hmm, I wonder if kotlin handles this, it does seem odd that we'd need to forbid it.

The JVM has a separate instruction for this (invokespecial instead of invokevirtual) which doesn't do dynamic dispatch, so I'd assume that's how they get around this.

The only somewhat clean solution I can think of is to make these member coros static, but that seems like a bit of a hassle too...
