+1. really need this coming along with babel-sublime

may i know if es2015 syntax will be supported? any time box for it?

Does it make sense to support `--password` or `RANCHER_PASSWORD` env variable. I think this is valid in non-interactive process like CICD.

@billiford will you add password support as well? maybe name them `--authUser` and `--authPassword` to differentiate from `--user`

Just PR to make it immutable supported #3
