### System information

Ubuntu 22.04.1 LTS

### Issue description

So far I've found these ones:

But there are likely more like them. They are invalid, at least in the context I encountered them here (at the beginning of a regular line of script)

### Steps to reproduce

Type `Anchor` in the code editor.

### Minimal reproduction project

N/A
r_result.insert(option.display, option);

						base_type.builtin_type = Variant::OBJECT;
						base_type.native_type = scr->get_instance_base_type();

				} else {
					return;

			case GDScriptParser::DataType::NATIVE: {
				StringName type = base_type.native_type;
				if (!ClassDB::class_exists(type)) {
					return;
