I'm just glad that most current browsers support all of ES2015, as it allows for much smaller bundles for them... I'm probably still going to need webpack+babel for a bit though, as I've been using async/await for a while. Though at least regenerator isn't needed in most places.

Beyond this, read this morning about F#'s pipe forward/backward operators, and that combined with the the F# composition operators would be a really nice addition to ES.
