Really loving those markdown style tests. I think it's a really fantastic idea that allows the tests to easily act as documentation too.

Can you explain how you came up with this solution? Rust docs code-examples inspired?

That concept has been formalized as part of the Python standard library.

Ah very nice! Did not realize this was a part of the standard library!

It's been there since Python v2.1 https://docs.python.org/release/2.1/lib/module-doctest.html

Here is the first announce of doctest I can find (1999) I think it's Python 1.5 time.

Elixir has this.

I use this in my books to show the output but also to "test" that the code found in my books actually works.

I love doctest as it works so well with a REPL but unfortunately it hasn't really gained traction anywhere I've seen.
