Simplify and reduce minified size without reducing functionality

It's pretty awesome, actually.

Well, I think it doesn't reduce functionality; we don't actually have tests for the "object literal shorthand", you know that? Though the code is pretty trivial, and I also tried it in the Node REPL (but seriously, it was trivial, of course it worked). I'm also about to submit another PR that removes the object literal shorthand altogether, so I didn't feel like writing tests I was about to submit a PR to delete.
