elm-repl creates elm-stuff and elm-package.json in the current folder #130

This is unexpected and can lead to littering if the elm-repl is terminated forcefully.

This also raises an issue if the user is in a folder where they don't have write permissions.

Another problem created by this behavior is that if I try to run elm-repl in a folder that already has an elm-package.json the repl fails if the project was created for a previous version.

I would have expected it to inform me that I'm currently in a project created for a different version but still run with the current core loaded.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

The point of the REPL is that you can explore your project. It's not just for playing around with expressions. That's why it is tied to an elm-package.json. If you just want to play around with the REPL, don't do it in an existing project.

I think it makes sense to refine this into a more specific recommendation.
