Fwiw, it also makes sense in AMD, where the set of dependencies can
grow and the desire to put every module on its own line becomes
desirable. I tend to do it for the array since you can be consistent
with the leading/trailing comma there, but not so much for the func
Allowing an "empty" comma after the param list could fix that. Also
allowing one before for the "comma-first" people would be nice.

This argument doesn't hold for server side approaches like node, or
build-step approaches like you use yourself.
Also, if you apply this argument to any new syntax the language never
changes, for better or worse ;)
Anyways, +1 from me. I'm tired of irrelevant diff lines...
