Following up on the initial version here, so read that first.
tl;dr:
Coalton is a statically-typed dialect library for/within Common Lisp.
You get to have your ML cake and eat it with the parentheses-all-the-way-down underlying implementation.
Previously, I had a way to write and run Coalton, I've now added (very basic) support for sharing some of these snippets too.
Steel Bank Common Lisp is fast enough to spin up and compile your snippets on the fly.
Why add sharing support?
Because I put it in the "coming soon" section earlier.
It might well be useless to anyone except me, and that's okay.
I have some uses in mind for myself. Feel free not to use it.
Usage
Sharing a snippet
Make a change, then click on the 'share' button

You should then see a popup with a copy-able URL

Share that URL, and when you or someone else pastes that in, you should see your original changes, with a short-lived overlay telling you you're viewing a snippet.

Bonus: Picking examples
I added some grouping within the example-picker, with "new snippet" being one of them (leads to a blank page)

Trying it out

[Warning: still not built for scale, still subject to random errors, etc. etc.]
Happy Lisping
