x = {
“a” => 1,
“b” => 2,
“c” => 3, #comment
}

Of course sometimes a "trailing" comma cause other browsers to just get confused, so it's best not. As to ending up with hard-to-track bugs... I fail to see how this syntax could lead to them. If your language supports it, why would it lead to bugs? You can do that in javascript, except one browser (cough) then gives you a null “last” entry in the array.

This is better than letting it go silently, as it could be indicative of an error -- a mistype or copy & paste problem, for example. Laziness is not practicality. Especially not if it makes it easier to end up with hard-to-track bugs. You can do it in most languages and it will result in a warning.

I always thought it was to make it easier for code-generators as they would never need to worry about the trailing comma.

You're right, though - it is a little tiresome to shuffle commas around when rearranging arrays. I think it’s the same in PHP, although I hardly ever leave a trailing comma deliberately.
