Cannot access member variable from lambda body due cyclic reference

[SomeRanDev]

Godot version

4.0.beta10

System information

Windows 10

Issue description

For top-level class variables, a lambda stored in a dictionary cannot reference the dictionary members.

Steps to reproduce

Assuming MyAutoload.gd is an autoload class, this code that worked in beta 8, no longer works in beta 10.

var f = func():
	MyAutoload.MyDict._str = "New string."

var MyDict: Dictionary = {
	"_str": "",
	"fun": f
}

# Parser Error: Could not resolve member "_OtherClass".

Autoload is unrelated however, just wanted to demonstrate how there's an inconsistent error if this is intended behavior. The following occurs regardless of autoload. If the "MyAutoload" part is removed from the lambda, a "cyclic reference" error occurs.

var f = func():
	MyDict._str = "New string."

var MyDict: Dictionary = {
	"_str": "",
	"fun": f
}

# Parser Error: Could not resolve member "f": Cyclic reference

From the mention of autoload, possible duplicate of #70495

@RobertBorghese Notwithstanding the possible duplicate, please join a minimal reproduction project when code is needed to demonstrate the issue, even if the code seems simple. It's so much easier for the developers to unzip the project and run it, rather than to create a new project and copy-paste the code.

Apologies for bad reporting, this occurs without autoload as well. Updated original post.

No problem! Updated post with minimal project! 👌

Seems related to this code:

godot/modules/gdscript/gdscript_analyzer.cpp

Lines 240 to 248 in b6e0603

	Error GDScriptAnalyzer::resolve_class_inheritance(GDScriptParser::ClassNode *p_class, const GDScriptParser::Node *p_source) {
	if (p_source == nullptr && parser->has_class(p_class)) {
	p_source = p_class;
	}
	if (p_class->base_type.is_resolving()) {
	push_error(vformat(R"(Could not resolve class "%s": Cyclic reference.)", type_from_metatype(p_class->get_datatype()).to_string()), p_source);
	return ERR_PARSE_ERROR;
	}

Just ran into this issue myself while playing around with Godot 4.0 stable. Small sample code to demonstrate:

var stats = {
	health = 100
}

var actions = {
	hit = func(damage := 1):
		stats.health -= damage
		if (stats.health <= 0):
			actions.die()
,	die = func():
		queue_free()
}

This currently errors on actions.die() with Could not resolve member "actions": Cyclic reference.
