I am kind of anti the leading semicolon. Of course I understand its syntactic need. But I kind of feel like, if it's worth iterating through a set of strings, it's worth giving that set a name.

var keywords = ['foo', 'bar', 'neat']
keywords.forEach(/* ... */)

I realize that my point undermines the entire purpose of this Gist. And in the intervening five months I had not even thought to try the new syntax. So it never caught on, even in its author's mind.

P.S. Happy new year!
