Lines 25 to 31 in a798e34

	if format!("{}", quote!(#path)) == "debug" {
	if format!("{}", attr.tts) == "( Clear )" {
	visible = true;
	}
	if format!("{}", attr.tts) == "( Hidden )" {
	hidden = true;
	}

Right now we re-quote the AST branch and transform them into text for string comparison, use something more idiomatic for this check.
