I don't have a suggestion for precise language, but I am really
uncomfortable with an error recovery rule that can discard tokens past a
top-level semicolon.  My preferred outcome for "@1; div { color:green }"
would be for the "@1;" to be ignored and the "div { color:green }"
considered a ruleset with a valid selector, namely "div".
