- `ac-stan` is not (no longer ?) available on [MELPA](https://melpa.org) - The examples available in the [README](https://github.com/stan-dev/stan-mode/) treat `ac-stan` as a "second-class citizen` (disabled by default). Do you plan to maintain an auto-complete feature for `stan-mode` in the future ? If not, what alternatives do you recommend (and why...) ?
