It's not hard to automate with raw gulp or webpack, but it does add a significant amount of time to compilation. It roughly doubled our incremental compile times. My team decided it wasn't worth it, but it's possible that a cleverer person could decrease the overhead.

I ask because I'm debating between trialing TypeScript or Elm for a personal project (I primarily work in Rust and Go on the backend/infrastructure), and iteration times are important when trying to get a frontend UI "just right".

You could just use TypeScripts ES6 output directly during development, using a browser that supports ES6 natively, then add Babel to the build chain for public builds that need to work on older browsers.
