Can you also please elaborate little bit @matthew-dean ?

@iampaandey I think the issue is here. It looks like the parser is a little naive, in that it allows any parenthetical (I think) after a selector, but then, within that parenthetical, it only accepts a single selector (this.selector vs this.selectors)
