Thanks for the advice about "Show HN:" :) It's my first post here, so I really appreciate it.

Opening a file works fine, as well! However, further loads are actually not from any cache. I decided against caching, because it becomes very difficult to add new language support if state persists between evaluations. To retain speed, Vim's asynchronous jobs are used if available. Complex operations will obviously take longer to show, but they will not interrupt typing. There's a big warning about trying to print infinite lists in Haskell, though ;)

The typical use case for Codi is trying out short code snippets to see if they do as you expect, or as a calculator where you can use your favorite interpreted language. Processing a lot of data is not really a good use case, but it's possible because the previous job is cancelled with every keystroke; it shouldn't be any slower than running it normally.

Pinning is a great idea. I'm not sure how it would be implemented, as anything you type in the buffer could be interpreted as a line to evaluate. Maybe a special directive like `!pin`, and escape exclamations via `!!`?
