### Minimal reproduction project

N/A
PatternNode *pattern = alloc_node<PatternNode>();
	reset_extents(pattern, current);
	switch (current.type) {
		case GDScriptTokenizer::Token::VAR: {
			
			advance();

				complete_extents(pattern);
				return nullptr;
			}
			pattern->pattern_type = PatternNode::PT_BIND;
			pattern->bind = parse_identifier();
			PatternNode *root_pattern = p_root_pattern == nullptr ? pattern : p_root_pattern;
			if (p_root_pattern != nullptr) {
				if (p_root_pattern->has_bind(pattern->bind->name)) {
					push_error(vformat(R"(Bind variable name "%s" was already used in this pattern.)", pattern->bind->name));
